Gigabyte EX58-UD5/Extreme Discussion Thread

LoL.. Mate, you aren't listening, this temps I am talking about are at stock, voltages are like 0.954v when idling.. I'm not even talking about the temps when I o/c this chip, so you talking about me upping the voltages are completely irrelevant..

And it has nothing to do with bad mounting or thermal management like you have stated, I have tested with 3 different HSF's, and I have reapplied TIM on several occasions.. and the variation between cores is only around 3c of a difference as well...

Even with the same cooler I used on my last chip which would have it idling at 36c there was still a 10c difference between these chips..

Like I said, this matter is over, as it has been dealt with..

Remarkable, I never knew such retailers existed....
I wonder what sort of premium one must pay for a "guaranteed" (R) OC'er?

I don't think anything like that exists in Oz, now there's a market!
If you're prepared to deal with the fanatics! :D

Yeah please do drop it now mate,
The thread is getting too focussed towards your dramas with a retailer.

I just could not boot to Vista for some reason. I pressed the Clear CMOS by the I/O plate, and restarted my PC and it booted just fine. The time did not change at all though.
Do you think my CMOS battery is getting weaker???

When you can boot in savemode its usualy a driver that :banana::banana::banana::banana:s up windows. You have two options:

A) Use a restore point, if you have one
B) Reinstall the OS

I would go for B.

I cleared the CMOS and it works now. I am thinking the culprit is the sound card driver.

Just wondering if someone could give me help on how to lock the multiplier in the bios. In windows the multiplier fluctuates between 15 - 21 depending on load.

You have to disable all Intel's power saving. They are under Advance CPU Feature

Thank you very much. I see you run Vista 64 do you have issues running SuperPi 32M? The only version that can pass 32m on my machine is SuperPi 1.1e everything above crashes. Starting to think its either Vista 64 or I need to reinstall.

When I ran SuperPI, it did not give me any kind of problem. Right now, I am trying to solve my problem with my sound card. It is a serious problem.

Disabling C1e and EIST in Advanced CPU Features will prevent the multi from dropping.

I personally prefer to leave these settings enabled in the BIOS, as it saves energy, and as far as my experience goes, they don't have any effect on stability.

Ya I was just trying to see what kind of SuperPi Times i could get.. Got a 9.77 @4.2Ghz but the CPU started at 15x multi and moved to 21 after the start..

I hope to your satisfaction at last, m8.

The true test of a retailer is when a deal goes wrong ... thankfully my recent purchases from them seem to be OK so far, but if there does turn out to be a problem, then I foresee nightmares getting it sorted.

OcUK are famous for bad after market service, reneging on assurances and delays, my and friends experiences, as well as googeling OcUK customer service back this up.

This time ... I swear, I'll never use them again, even if I have to wait for other UK retailers to get stock in.

In fairness, Rich from OcUK seems like a decent guy, but he's bound by his employers ... I have no grudge against most OcUK staff, its those in charge that are at fault and why OcUK's reputation seems to be going downhill fast again.

anyone is using this ram "TR3X6G1600C7" with his UD5 or UD4P, I can get a stable 200x20 configuration but I must have all the memory sub timmings @ Auto, if I try to change for exmaple TRTP [auto set it to 9] for 6 like the SPD says, it will boot but give me error about TPM encryption press F10 to continue then it will recover from a bad OC and it won't boot again and I have to clear cmos, I tried with XMP profile and without XMP profile, with some seach I knew that this ram use BBSE Elpida chips, I'm using the latest beta bios.

Sorry, I do think I answered this for you at Tweaktown maybe not, but I was a bit hasty in my reply and forgot to tell you the rules concerning settings. Your mention of TPM Error screens made me feel I had to chime in and help you out with at least a reply, then it grew!

I spent a long time speaking with Gigabyte and the BIOS Engineers on the TPM error issue when setting advanced memory timings, so I thought I would let you know about all the rules and my findings. The error you are seeing I do believe is not caused by tRTP, and you can verify that by setting everything to auto and then only trying to set tRTP.

I do believe you may be seeing this error due to other incorrect settings, please spend a few minutes and take in the information below. Hope this helps you out, I know I was frustrated for a long time in regards to TPM Errors and memory timings. I think it is all resolved now though :D :up:

You must follow this rule when setting tWTR:

tWTR Must be Write to Read Delay/Same Rank - (tWL + 4)


Also because these settings can cause the same or similar TPM errors for you if set improperly these rules must also be followed:

tWTP Must = tWR + tWL + 4
tWL Must be CAS Latency -1


** Sometimes I find tWL does not correspond correctly in regards to the rule and may be +1 what it should be, so keep that in mind also when setting either tWTP or tWTR. So find and set this, and test with Memset to find the actual Value in the BIOS then apply to the above rules. For instance I found at CAS 7 I can only set tWL to CAS Latency + 1, around 1600Mhz that is. And at CAS 8 I could either set tWL to Match CAS Latency value or CAS latency +1 again.

The above rule concerning tWL should be CAS Latency - 1 was given to me by Felix. So I do believe it is correct, but maybe not for X58 anyway? Not sure if he tested this or if it actually applies to X58 as I could never get it to apply properly following those rules. I have not spoken with him in a few months about it though, maybe he has done more testing or reading and could better answer you now on tWL and X58 as to why this happens.

And there is an offset between what you set in the BIOS for Write to Read Delay/Same Rank and what you are shown in windows/memset, this varies from different main timings, multiplier and freq, so you will need to test setting at a given speed until you know what the offset is. Then you can adjust the rest or not accordingly to change this value. I also believe this is directly affected by tWTP and thus also it's related settings. More thoughts by Eva2000 on this are linked below

Additionally the above statement on tWL Rules, must follow the intended tWL Rule (CAS Latency -1) and not the BIOS settings for tWL.

** This statement may be disregarded after some quick testing with F9c (UD4P) for a reply to this post. I will leave it for others just in case it may apply to their board or if they are using an older BIOS. It seems after a quick test to reply to you, that this issue I found with previous BIOS in regards to the above tWL rule may have been corrected now. I can set tWL to CAS latency - 1 now, so looks to now be resolved.


The Write to Read Delay / Same Rank setting is in the turnaround settings in the advanced memory timings page, per each channel

Eva2000 also posted some of his strange finding for a few settings in relation to DFI Boards. I am not sure if his findings are the same as mine, or if we both have different thoughts or therories on the matter.
http://i4memory.com/f80/initial-note...8-t3eh8-18821/

I was doing some tWTR and tWTP Testing but got side tracked and have not ventured further into things yet, but I have fully tested a wide range of tWTP and had an ongoing discussion with Gigabyte several months ago on the subject of memory timings and getting the same errors you mention when setting certain ones. After some work and several Beta BIOS's to try and resolve the matter I finally got them to add in tWL and tWTP to try and alleviate the issues mentioned. I just have not had time lately to test things in regards to this matter and so our discussions with the BIOS engineers and testing have not continued since late march.

I have ran a quick test for you just now, hope this can better show you with the above rules how things apply.

Here is a screenshot of Memset with the settings below applied. BIOS F9c UD4P

tWTR ...................................... 2 (Must be Write to Read Delay/Same Rank - (tWL + 4) So here we have Write to Read Delay/Same Rank 12 - tWL 6 + 4 = 2
tWR ........................................ 10
tWTP ....................................... 20 (tWTP Must = tWR + tWL + 4) So here we have tWTP 20 = tWR 10 + tWL 6 + 4
(Grrr After all the hassle and testing I went through on this setting, today I find a variance of at least 2 is allowed in the current BIOS I am using!!! Anyway, stick to the rule until later, then you can fiddle :D)

tWL ........................................ 6 (tWL Must be CAS Latency -1) So here we have CAS Latency 7 - 1 = 6
tRTP ....................................... 6


http://i26.tinypic.com/es9tmh.png


And the BIOS Settings I used for this quick test to show you how the above info works when setting these.

http://i27.tinypic.com/s25pwm.jpg

http://i28.tinypic.com/s48j7o.jpg


Please note, these settings may or may not be optimal (likely not) I just set these as a quick test to verify that the TPM boot issue was not present and to try and show how these settings and rules apply to all things considered.


Sorry for all the confusion this post may cause but I had to reply since this had bothered me for quite some time. I spent several months and MANY Emails back and forth trying to work with Gigabyte and the BIOS Engineers to try to get these settings corrected and added to the BIOS. And with our discussions on the subject stopping back in March due to my lack of testing time and never getting back with them on the subject I was not sure if they had fixed things yet or not, and which of my previous findings still applied.

Hope this helps everyone, and not makes things worse :up:

@ Eva2000

Care to chime in with your additional thoughts or findings if you are reading this? It would be greatly appreciated!!

Thanks LSD, your settings worked fine and CPUTweaker showed correct values.

What concern me now is the "Round Trip Latency" I noticed that this value keep changing every time I reboot, sometimes it will be 51/51/54 and sometimes it will be 50/52/55, it is better to set it manually?

* I noticed in your screen, RTL is reporting 56 in bios and 55 in CPUTweaker, so I think your RTL is changing automatically too everytime

It can have a big effect as it may throttle back the CPU and undervolt it too much causing it to crash out as you will still have a high BCLK. Ive always disabled it on big overclocks since the Core2duo's to keep everything level and stable. It will also play with your idle temps as the voltage is pulled from the chip and reapplied dynamically.

The only time I have noticed these settings alter my voltages on the UD5 is when I have Vcore set to auto, but when I manually set Vcore and have these options enabled, the only thing that it appears to alter is the CPU multiplier.

Though I am only going by software that monitors voltages, they could very well be changing, and just the software doesn't pick it up.

But as I said, when I put everything back to optimized defaults in the BIOS, when I check CPUZ my Vcore is around 0.9445v idle, and they shoot up to 1.1675v when I put a load on it.

I have tested my o/c with these settings enabled and disabled, and I haven't witnessed any ill effects.

No, those settings are not optimal like I said in my post, I just set them like that to show you that they all do indeed work. You will need to find your own stable settings, so please do not use those as they are not stable or optimal, only intended to show you the settings all work.

What you see in the BIOS on the left can and should be ignored. Those are almost always (99%) incorrect and not used. Of course sometimes a few are correct but you should just get yourself in the habit of not even paying attention to them to be on the safe side.

RTL can be affected by many things, QPI/Vtt voltages and QPI Speeds, main timings, and other timings as well.

I made a small note on setting them manually here, but please do read Eva2000's tips as well also mentioned in the above linked thread

Did you uninstall your older one? You must uninstall the older version before you install the new one. So just checking

I was wondering if anyone could tell me why EasyTune6 doesn't monitor my +12v and 3.3v?

I only see Vcore, +5v, and VDimm, but I have seen other peoples screenshots where it shows +12v and 3.3v values as well.

Question about vcore & Vtt...

If I easily pass LinX over 20 passes and Prime 95 on low and high fft's.
I've found the sweet spot for Vcore. The next notch down fails LinX. Should I bump the sweet spot up 1 notch to ensure stability or assume solid stability from testing?
Vtt, I started at 1.355 and I'm down now at around 1.2*. How should I know where the sweet spot is here and should I apply the same principle of, once you sweet spot is found add 1 notch?

Different models have different sensors, I only see Vdimm and +5V on the latest easytune, not sure about in the past though? So it could be easytune errors, not sure

I do know everest shows vcore of course, and Vbatt, Vdimm, and +5V on the UD4P. No 12V and this has always been a constant. I do think some boards monitor the 12v and others do not. It should match up with what you see in the BIOS Health section, so in my case I do believe Easytune has a big now that I say that because Vcore is not shown in the monitor tab as in the BIOS.

I will report this to Gigabyte and see what they have to say

Help please!

OK I was advised that this might add problems that need working round but I had the opportunity to purchase another 6gb cheap new so I added another 6gb to my rig.

I now have the dreaded problem on post where it won't boot and eventually resets itself.

I have 1600 OCZ ram (12gb)
QPI Link: x36 (7.2Ghz)
Uncore: x 16 (3200Mhz)
Clocks are set as recommended (worked fine with 6gb)..
8
8

QPI/VTT I've put back to 1.355V for the moment.
IOH Core: 1.160v
Dram: 1.660v
CPU PLL: 1.800
QPI PLL: 1.200
ICH I/O: 1.500
ICH Core: 1.100v
Dram term: 0.750v
All other ch-a ch-b ch-c etc etc left on auto.

CPU's at 4.2 (1.35V) and was stable via LinX and Prime on 6gb.

Any ideas please what I need to change to get 12gb working ?

(I've just about got my head around things and now i'm baffled again)

I just tried dram at auto and it booted... hmm... wonder if I should try one notch above 1.660?

OK that never worked. :(

Need help lads please.

Anyone??

For 12GB you may need to set Dram voltage to 1.68-1.7 and IOH to 1.20-1.28

Would there be any limitations with the RAM controller on the CPU itself?
Also I read that going over 1.65v could damage the CPU???
http://www.tomshardware.com/news/int...tage,6464.html

Quote:

“According to Intel CPU spec, DIMMs with voltage setting over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage settings below 1.65V.” According to Iain Bristow, spokesman for Asus, “the sticker had been placed on the motherboard after Intel’s recommendation.”

I currently have..

4.2 OC
Ratio: 20
BLCK: 200
SPD: 8
And Intel Turbo tech boost on to give me the 21 for added stability that seems to work well.

Any help really appreciated.

You only need to be sure you keep the dram voltage within .5V of the QPI/Vtt is all. It is not a 1.65V limit

Set command rate to 2T for 12GB.
Also increase IOH to 1,2-1,25V and VTT to ~1,4 that should do it.

1.4 :|


I'm getting a little concerned about the dram been within .5v of vtt... not something i've known about. (ops scotty)

What should I be setting that to?

you will hear both sides to the argument, my 1866 dominator gt's require 1.65v and VTT of 1.6v according to Corsair to run at their rated speeds...

More than 1,45V VTT on air WILL kill your IMC sooner or later. I killed the 3rd ram channel on a 940 after 2 weeks at 1,52V - on phase change (cold is supposed to help).

Good lord :(

I have a quad rad but don't like the idea of this vtt volting been an issue.
So 1.4 is perfectly safe?

Should I even go 1.4 on vtr to try to get
the 12gb working ?

At the moment on 6gb @4.2ghz...
I have vcore 1.3 and I did have vtt as 1.355 (?) but I've been lowering it and then Linx testing etc
it's been stable.

Can you go as low on vtt as you need to as long as you maintaint the .5 between vdim and vtt??

I was wondering if anyone here knows what is happening with these EX58A series boards?

As someone posted on OcUK forum that they contacted Gigabyte via e-mail and another guy actually called them up to see when we were likely to be releasing these boards, and they were told that they wouldn't be hitting the shelves anytime soon, if at all.

Here is the post I am referring to:

http://forums.overclockers.co.uk/sho...6&postcount=34

I remember one of you guys on this thread saying they should be here by next month, but if what these people were told is true then we probably wont be seeing them for a good while yet, or maybe never.

I was actually looking forward to these mobos becoming available, but I guess that isn't going to happen now. :(

You dont need 1.4V VTT for 12gb to run, but it all depends on the CPU, the speed at which your rams opperate and on the bios version you are.

Im on 12gb with 1200mhz @ cl7 T2 running with VDIMM 1.65, VTT 1.355, Vcore 1.28x (Drops to 1,245) and works without problems so far.

Though im still on F4j cause all the other versions need either more VTT or more Vcore to be stable.

Yup, with on exception that tras was 20 instead of 24

But you could also try 1600mhz with cl9 or whatever works best for you.

Maybe i can get my lazy ass to work and try to figure out a new setting for the latest bios. :p:

I do believe over 1.35-1.4 is fine, some XMP actually have programmed settings of 1.6 or more.

I made a post at TT about this, which links to OCZ's qualification and testing of some of their modules at 1.6V QPI/Vtt at stock speeds.
http://forums.tweaktown.com/f69/post...97/#post312297

As long as you keep QPI/Vtt within the .5 range you will be fine. Alot of the 1.65V ram discussions were made before anybody knew anything. I think if 1.6V was a dangerous QPI/Vtt voltage OCZ would not test, validate, and program their modules at this setting, nor would the publish it in public as they do.

Of course voltages are always up to the end user to decide what to use, but just keep in mind certain things (High Speed/Tight Timings) will not be possible without stepping outside of the ranges that have installed fear into everyone. Please do go have a look at the bove link, then follow the link in that thread to OCZ's page and have a look at some of their modules XMP Programmed settings.

bugger it.....

I'll stick with 6gb :|

Which ever way I do this it looks like speed some how is sacrificed.
So until there is someone who can confirm that I can go 12gb somehow without needing to loose much speed.
I will keep things as they are... luckily I can sell on the ram to someone who wants it.

OK...

Before I decided to try out 12gb i'd been working on stability on 6gb and I've been using the following.
Can anyone please highlight any problem areas for me?

6gb set up...

Clock 20x (with intel boost 21x)
BLCK: 200
Uncore: x 16 (3200Mhz)
QPI: x36
CPU Clock drive: 900mV (is this the best setting?)
PCI Expess Clock Dive 900mV (is this the best setting?)

SPD: 8
Timings.

LLC: Enabled
Vcore: 1.356 (working on a 3.5v)
QPI: 1.175v
IOH: 1.160v
Dram: 1.660
CPU PLL: 1.8v
PCIE: 1.5
QPI PLL: 1.2
ICH i/o: 1.5
ICH Core: 1.1
Dram Term: 0.750v

Is there anything other than vcore I should be looking at lowering or highering?

Thanks

well i can tell you now i can get my dominators to throw memtest errors when i back off the VTT at 1900mhz. Linx is great but it wont show errors all the time, memtest finds errors before i see any sign of instability, it likes to burst my bubble aswell :shakes:

ive just left it on 1.65ddr and 1.6vtt for now...its also a pain getting 1T stable at 2000mhz :(

So did you try the new BIOS's and raising B2B settings? This is supposed to help stabilize at 2000+. I have not used any of the new BIOS's yet as I am in the middle of a review, but I do know that is supposed to help at higher speeds like that.

I just OCed my i7 920 D0.
On the motherboard what are the 5 blue light, next to the CPU temp LEDs, for?

The DRAM and QPT/VTT voltages should not exceed 0.5v, right?
Also, what is your 920 D0 vcore @ 4.0Ghz? (turbo disabled)
QPT/VTT Voltage @ x36?
I know we don't have same vcore and QPT/VTT, but I just want to get an idea how high the voltages for i7 920 D0 stepping.

Since I am off of work today, I OC just the CPU, and downclock the RAM and Uncore.

CPU Blck Freq is the 5 Blue LED's

Keep your QPI/Vtt within a .5 range of Vdimm

The 5 blue LEDs are all lit up, is that good or bad?
The temperature LED's are not on, I guess because I disabled the thermal monitor.
Right now, I left the DRAM on auto since I downclocked my RAM & uncore.

What about the Voltages of 920 D0?

EDIT:
Can someone please post your 920 D0's BIOS 4.0Ghz template?

Thanks

RTM... :yepp:

The blue leds are the overclocking leds.... the higher you oc the more leds are shining... its all in the manual page 26 and onwards.

havnt had a chance to play with some of the smaller settings :) just finding the max OC of the chip at the moment then i can come back to getting more out of the memory :)

Sounds like a plan! Good luck with the tweaking!

Ya, B2B is supposed to help at high ram clocks, here is a review on the setting if you have not seen this already

Here is the post I am referring to:

http://forums.overclockers.co.uk/sho...6&postcount=34

I remember one of you guys on this thread saying they should be here by next month, but if what these people were told is true then we probably wont be seeing them for a good while yet, or maybe never.

I was actually looking forward to these mobos becoming available, but I guess that isn't going to happen now. :(

Yeah that pisses me off, frackin :banana::banana::banana::banana: teaser... :D

Makes me want to go buy Asus's equivalent revision that was also coming out.
Can anyone remember what that one was called?

So is Asus also not releasing a revision now or what? Just sounded that way by you said that.

I was told previously they would be released when P55 was released. I will be able to find out for sure after the 31st so stay tuned :up:

Well, one of the guys that works at OcUK posted on the forums saying that they had a Gigabyte rep in last week and they confirmed that the EX58A boards have been cancelled altogether now. :(

http://forums.overclockers.co.uk/sho...9&postcount=26

@ Jalyst, where did you hear about the new Asus board revisions?

I have been thinking about an RIIE for quite a while now, as I really love the design of that board, but if they are releasing new revisions, then I will wait for these to be released to see what they are like before I make another purchase.

Im not particularly sad that the X58A got canceled, just means longer support for the X58. :)

yup doesnt worry me either, on another note has anyone noticed a beta bios that can correct the vdroop? does get quite annoying once you start cranking the voltage up :(

i have llc on but it doesnt seem to do anything.

What would be the X58A ?

Ya, I have heard both said second hand by Gigabyte reps. Maybe it is true, maybe not? I will be able to find after this next week directly from Taiwan

Anyone friends with Dinos22 or Hicookie should be able to tell us for sure, if anyone is please PM them and see if they can get an official reply about it all.

Just FYI

195x21 / X36 / mem x8 @ 7,7,7,20 / HT - ON
Vcore 1.4875v (bios)
VTT 1.46v
Ram 1.76v

Been running my C0 nearly a yr now with those voltages, with a UD5 and air cooling, still not suffered any problems yet.
Oh, and just to add that's with the F4 bios.

Linx is probably the best with OCCT, though i find Linx will find errors within 25 minutes or it wont, usually within 10-15 though :)

OCCT doesn't heat up as much though so it might be stable at the same speeds ;)

if you want to test ram to perfection then a combination of memtest and Linx.

I use a mix of LinX, Prime95 (Blend Test), 3d Mark Vantage, and gaming for hours on end!

I use LinX, Prime & SuperPi 32m......along with general everyday usage (gaming, encoding, benchmarks, internet etc etc).

I used LinX too. When I used Linx, I used 50 or 100 ran. I also use Prime95 and Intelburntest.
I could pass those, but when I ran prime95 small ftt, I got BSoD it was either 0x000000eb or 0x0000001e. I am thinking these BSoD are could be driver problem.

There was supposed to be an asus based x58a too, but like the gigabyte i think it's been axed :-(
I tried to google around for evidence of it becoming available but nothing....

So can you find out for both Asus and Gbyte for sure when you go to Taiwan?
How will you do that, do you have contacts at both organisations?

I won't be going to Tiawan, I meant my Contact at Gigabyte will be back in the office after the 31st. So I would ask him then, he is pretty fast at getting back to me and the last he told me (in June) was that they would be released at the same time as P55 so they could release all the new Smart 6 features at once.

Of course things may have changed since then as we know, but I will find out from him once he is back next week.

Sorry, I don't know anyone at Asus though, Just Gigabyte

Mate, you are only using 512MB of ram out of your 6GB, no wonder you are passing LinX!!!

Try using max available RAM and then see whether or not you pass the test.

Also, instead of using 20x200 for 4GHz try setting Bclk to 191 and then enabling Turbo Boost for the 21x multiplier.

I found with my last 920 that it needed less Vcore and QPI/Vtt when using 21x191 instead of 20x200...

But if you are BSOD'ing with Prime95, I can pretty much guarantee you will BSOD with LinX when you set it to use the max available RAM instead of just 512MB.

@ BluntSmoker,
I am going to try that.
Since I don't feel comfortable with most of my voltages on auto, what is your voltage on IOH Core and QPI Core?

I just get a BSoD 124, I just add change my QPI/VTT voltage from 1.315v to 1.335v.

Hi, I'm new to this forum, so go easy , eh ...

Specs are in my sig. VCore is 1.28125v with LLC enabled, Vtt is 1.2v, BCLK is 195 with Turbo on (195 x 21 = 4.095 Hz). HT is on (8 threads). Mem ratio is 6 giving 1170 MHz. Uncore multiplier is 16. Vdimm is 1.64v. IOH and ICH core are 1.2v. Everthing else is stock (I think). All power saving settings are on. F7 bios. Memory settings are 6-6-6-16 and Turbo.

I can run Prime 95 stable (v25.11, build 2) for 5+ hours. with a max temp of 79 deg C (recorded by Real Temp 3.0.) for the hottest core (the lowest is ~74 deg C). Idle is 40 / 41 deg C (for an ambient of 25 - 26 deg C).

So, all good so far.

However, when I run LinX (v0.6.1) after about 35 seconds I get an alarm from the MB speaker, as if a fan has failed, but max core temp is only about 74 deg C. However, even if I set all such alarms (including the CPU temp alarm) to off this still happens.

Any clues as to what is causing this? As it stands, this is preventing me from pushing higher:mad:

P.S. I have briefly run Prime 95 for ~10 minutes as a check (after which I stopped it) with a BCLK of 220 with Vtt at 1.24v and a low CPu multiplier of 12, so I am pretty sure that the board is good to go higher than 195.

Can someone explain what exactly are these for?
IOH core
QPI PLL
C3/C6/C7 State Support
CPU EIST Function
Bi-directional PROCHOT
CPU Thermal Control

Yeah you need to run Linx at the highest memory setting for proper testing :yepp:

With 220 you might be right on the edge of stability as mine seems to hit a BCLK wall at 220 and likes to BSOD at anything higher. I can run the chip at about 4.6ghz but no matter how much voltage i dump into the core i cannot get any stability out of it past 220. Might have to try winding the multipliers back and see if it still has an issue.

Try dropping your ram command rate to 2N instead of 1N that helps with stability alot, you might need more VTT depending on the speeds your pushing from the 12GB

Try 12x or 13x Uncore (since it's 2x or 2x+1 your memory multiplier).


By the way, welcome to XtremeSystems. :clap:

SimpleTECH,

Thanks, I recall I had trouble posting with Uncore lower than 16, but I will try your suggestion and see if it helps. Appreciated.

BTW - how much better is your w/cooling over air? I am tempted to go down the HK 3.0 route but I'm not sure if the gains are worth it (obviously this is not a real value decision - as a good w/cooling setup would cost me ~£240).

@Mr.Fixit, you will need to run your mem multi @ 6x if you want to use anything lower than 16x on Uncore, as the rule is that Uncore should be twice that of the RAM multi, you can set it higher than double, but if you trying going lower it results in BSOD.

I have found that with my UD5's, I cannot use the 12x Uncore multi when using a 6x mem multi, that refuses to POST for me altogether, when using 6x on mem, I have to use 13x uncore for my system to POST.

As for WC, I am going to be purchasing parts to setup a custom loop for my rig, I will be using the HK 3.0 as well after seeing a few builds where people are using them, as the temps compared to air are fantastic.

I seen someone on another forum with temps of 61c full load @ 4GHz, that is amazing compared to air imo.

I am gonna need some help with RAM timings
I can't pass linx and prime95 now. When I ran Linx, it stopped at 9 sometimes at 13 passes. When I ran p95 blend, I got BSoD which were 0x0000000A, 0x0000001E and 0x0000003B.
I have a feeling the culprit is my RAM, but I could be wrong. I did not get any of these BSoD's 50, 101 and 124

Thanks, I am already running with the x6 mem multiplier. I too tried x12 for Uncore with no Post, hence why I set it at 16. But I will try 13 as you suggest, although I am not sure whether this will stop the alarm going off.

I look forward to seeing your before and after w/cooling temps. I assume you will need to use a triple rad in the loop.

EDIT:

OK, so I have just tried the 13x Uncore and it posts OK, but again after about 45 secs of LinX I get an alarm souding. So, what can this be due to? It's not overheating or throttling (around 74 deg C). Any more ideas to try anyone? BTW - LinX will keep running OK, so it is just the alarm problem I can't live with - it's way too loud!

depends on many factors, mine still hits 80c with the HK v3 and a TFC 360 radiator when im pushing 1.35-1.4v @ 4400mhz or higher, though it might have helped if i could mount the HK the right way across the cores but the caps next to the socket on this board stop that...

Okay very keen to know...
So please let us all know once you hear from him.

Thanks!

I made it. All I did was pump the vcore a little and fixed the problem.
I was fooled by the BSoD that I was getting that was why I thought I did not need to add more vcore.http://i337.photobucket.com/albums/n...stable4GHz.jpg
http://valid.canardpc.com/cache/banner/673884.png

WTH!!! I can pass Linx now, but I could not pass Prime95 blend.
The BSoD I got was 0x0000003B. I think that error is for display driver's bug or something.
I am going to reinstall the display driver and re-run P95 blend.

Do you guys have any input about this?

I had BSOD's with the new WHQL 190.6x drivers from nv.....did my head in!!

Nope, but you can get the 21x multi by disabling some of the power saving options (I disabled all) and enabling Intel Turbo Mode.

Apparently, it is possible to FORCE the x21 multi....I'll see if I can find the post over on G3D :D

With this board ( I owned the Extreme...same :banana::banana::banana::banana:), you can only select 20x multi then add the extra with Turbo Mode.

yep you can do it on any x58 as long as it's running reasonably cool.
see Turbo mode

:lol: I know don't even go there :ROTF: Alonso is a great loss.

Got my replacement chip today, and I am up and running again @ 4GHz with normal temps!!

Idle temps are 36c, and full load hits about 79c.. although my system still isn't inside the case yet, so I assume these temps will rise a little bit once it is all back inside the case.

I am just happy that I can get 4GHz stable again!

I was supposed to get my 2nd chip today that I ordered for my Fiancees build, but OcUK sent it out with 2 day delivery for some reason... even though it says on their site that I was supposed to get next day delivery..

It will be here tomorrow though, hopefully it is a goodun as well :D

::edit::

Temps will rise a little when the rig is build up inside the case right?

Or will they go down because of my 5 x 120mm case fans blowing air across everything?

They will usually go up because your ambient temp will be higher.

That's what I thought, but I just wanted to be sure.

Thanks mate ;)

Nice Blunt, what is the CPU batch and what voltage did you use for 4GHz?

I haven't really tried to tinker with my voltages to see how low I can get them, they are currently at 1.2815v in the BIOS (1.264v in CPUZ), with QPI/Vtt @ 1.285v, and I have tightened up my RAM timings to 8-7-7-21-1t as well.

I've been trying to get it stable at 4.2GHz today, but it isn't happening for me, I have managed to get it to stop BSOD'ing in LinX and now it only stops because of errors, so I am getting somewhere at least, although I think I am just going to keep it at 4GHz until I get the chip under water.

I will be building a custom loop in the next few months, I am just buying up my parts slowly.

I've managed to get a 2nd hand EK GTX280 block and backplate from OcUK Members Market for £35, so I am well happy about that.

And I'm sending my TJ10 case off to ChilledPC to have them mod the roof so I can fit a 120.3 radiator in there, and they will be powder coating the internals red for me also, as well as putting some holes in the mobo tray for routing cables to.

I should hopefully have all this work done before the end of the year, I can't wait!!! :D

Still waiting on my second chip to be delivered, I thought it would have been here by now...

hi blunt,
just wondering... what version of dominator mem do you have?
the errors in linx might be due to memory
i had a kit of the ver2.1 dominator mem which wasn't very flexible at all. best i could get out of them was 7-8-7-21 1T

Hey Pyr0, my Dominators are v3.1..

Like I said, I didn't really play around with it enough to try and get 4.2GHz stable, I think if I did mess around with them and tried to loosen up RAM timings I might have managed to get it stable.

When I first tried it, I kept getting 124 BSOD's, but raising QPI/Vtt stopped the BSOD's, and LinX would just stop due to errors..

This is the same thing that happened when I first tried for 4GHz, and I got that sorted out by raising QPI/Vtt a little bit more.

But tbh, I am just going to leave it at 4GHz until I get this chip under water.

yeah i just mentioned it cos i was playing with my mem last night trying to find out what voltages it needed for 1900 stable(ish)
i also stopped the 124 bsods with more qpi vtt, but then linx was just giving errors until i raised mem voltage

You have your dominators running @ 1900Mhz?

What timings are you using for this?

And what do you have your CPU clocked to?

My Dominators struggle to do anything more than their rated frequency, I am starting to hate this RAM actually, I think I will buy another brand of memory soon to replace these ones.. When I bought them I thought that I would be able to O/C them by a couple 100MHz and for them to run without any issues, but that just isn't the case for me unfortunately..

Even at 1688MHz they give me BSOD's all over the place.. though in saying that, I haven't really tried using more VDimm than 1.65v, as I am afraid of damaging my processors IMC.

Which RAM would you say is the best out there atm for overclocking?

I have heard that the Patriot Viper 1600MHz is supposed to be good from a few people, they aren't to badly priced neither, and the color of their heatsinks would go nicely with the UD5 color scheme as well!

tbh i haven't tried any other sets, so cannot really recommend anything :(
i still have to check full stability with this kit, as i've only been testing by running 25 loops of LinX for now, but so far managed
1600 7-7-7-21 1.70V
1600 8-8-8-24 1.56V
1800 8-8-8-24 1.68V
1800 9-9-9-24 1.60V
1860 9-9-9-27 1.62V
1900 9-9-9-27 1.68V

at this moment i just have them running at 1600 7-7-7-21 1T (200 bclk) because it only needs a low qpi/vtt

while testing i just kept my cpu at or under 3.8Ghz cos its a crappy C0 chip, sometime i'd like to try a D0 i920

Thanks for posting your timings for these clocks mate, I will give this a go later on today and see if I can get my modules stable, I never used anything higher than 1.65v VDimm because of the Intel specification, but I have read a lot of posts on here where people are running 1.8 to 2v VDimm without any issues.

Do you know why Intel have said that 1.65 is the limit?

Having them running at their rated speed with only 1.58v is not bad actually.

What did you have the advanced timings set to when testing these clocks, did you just leave them on auto?

I always set my advanced timings to the same values as the XMP profile sets them to, I haven't actually tried playing around with these yet.. I just have mine set to 8-7-7-21-1T atm, and it is stable with the CPU at 4GHz, I let it run 20 passes of LinX using all available RAM, and I left it running Prime95 Blend Test overnight to, and it was still going when I got up this morning, so I would say that this is stable.

RAMs are giving me stability issues too in new LinX (i think it is RAMs atleast). I'v got OCZ Platinum tripple channel - http://www.ocztechnology.com/product...triple_channel

I'v tried to lose the timings to 8-8-8-24 and bupmed the VTT to 1.35V and VDIMM to 1.64V, still cannot pass LinX (usually BSOD after 2 passes). My multiplier is set to 6.0 and uncore to x16. I am at 4GHz btw (190x21).
