Good luck to you too.
But just stop for a second and consider X79/39xx combo.
I've bought M4E/2600K&2500K, tried it and it was very short fun. Sold both CPU's and left M4E to wait for IvyBridge.

As I have found out, this platform is useful if you are engaged in engineering either scientific calculations, or video coding or something similar. In games, productivity of these processors same as at 1155, even if to take SLI decisions (i talking about 2-way SLI).
And as one processor 3930К here costs as much how many the motherboard 1155+2600К+about 8 GB RAM, and the computer at me is used basically for games the choice is obvious.
Nevertheless, thanks for council. I, probably, will return to this question when the prices on 2011 will fall to reasonable level.
Wow the next RST driver will support TRIM in RAID0!!!!

lol, yes we know... lets just hope the performance comes back up with it because some of us lost raid0 performance with this 11.5 release...Quote:

normally, there'll have the IvyBridge-E 22nm on the platform LGA2011 ;)Quote:

Yes lets hope someone can do it properly without any negative side effect. I was forced to downgrade from the 11.5's back to the 11's because I was having so many application errors and most of my apps began to crash trying to launch them. I realized that I had recently only installed TWO newer drivers, ATI drivers and IRST drivers 11.5. So on the day before Thanksgiving I decided to drop back to the Alpha 11.0's and sure enough all my errors with applications magically returned. I am thankful that the 11.5's did not cause any corruption and that everything seems to be spot on back to normal without a re-install of Windows...Quote:

So, finally he could afford a great system, but now its me who has to be frugal with my upgrades these years, lol. So I am thinking of getting 12GB OR 24GB of the fastest possible memory, and try and find a retired 6 core Gulftown for a good price. Nothing short of a ROG motherboard quality will do me, so this way I can keep my ROG RIIIE a little while longer (we all know the build quality should last), and just throw some faster components at it. I think that "should" satisfy me a while longer. haha I hope...Quote:

What a fail. Got a red Phanteks cooler ordered :)
curious question, does this board run with 48gb's ?
saw some videos on youtube of some gigabite boards doing it :p
The black edition does officially:

Nice run there, new old kit?
I also decided to reinstall my 2 Gb geil modules which I forgot to mention. The new cooler Im getting wont fit with anything other than low profile ram, I dont even need more than 12 Gb, and 1800 Mhz cas 7 is a lot better than 1600 Mhz cas 9 for gaming.
I already tried with just 3 modules and couldnt get them stable at 2000 Mhz, but that doesnt really matter when they do 1600 6-7-6, or 1800 7-8-7.
4 Gb modules will never do that, and there are no better low profile 2 Gb modules available than these geil ultra series ones.

Mushkin sells a 1600MHz 6-8-6-24-1T 3x4GB kit also... Not a stretch to think it would do 6-7-6-24-1T.
You cant get those in the UK though, I've only been looking at whats available to buy here on OCUK or Memoryc unfortunately.
Even if they did come to the UK, the prices would be too high. Triple channel memory kits have been phased out for a long time now, at least in the UK you cant anything decent for X58 unless you buy 3 lots of dual channel kits.
nice to see x58 #livingstrong

Hrm, I think the bandwidth looks woefully low on AIDA there spool? Weren't your old results like 22k-21k-24k?
No C1E and uncore is less than 2x RAM speed so that looks about right doesn't it?Quote:

How old`s you're Rex3?
You have 6x4 Gb Geil Ultras according to your sig?
If you can reach 1800 Mhz Cas 7 with 6x4 Gb sticks I wouldnt worry at all, thats impressive for 24 Gb.
I've used these sticks in both my UD5 and R3E with 2 CPUs. 1800 Mhz Cas 7 is no problem, but pushing any higher on X58 is a major PITA. I can boot at 1900 Mhz Cas 7 with all 12 Gb detected, but there is nothing I can do to get it stable, even 1.65v and 10-10-10-30 2T timings are unstable when going over 1866 mhz.
Any better ram than this stuff is major rare in the UK, and even if we do get it, it costs too much for ram.
4.66 Ghz @ 1.425v on the CPU with HT off is somewhat stable with 1866 Mhz Cas 7 ram:

It only made it to 22 mins in Linx, but isnt having any problems so far in gaming.
I was also crazy enough to order a 512 Gb Crucial M4 because they were on a daily offer at £499. Thats a lot of money on an SSD, but I will ditch my Raid 0 F3s for the 512 Gb M4 for my gaming drive, and keep the two 2 Tb F4s for backups and non game files.
Pretty much most of my money gone on the I7 980 + Phanteks cooler plus a 512 Gb Crucial M4. Yes I am crazy.
Oh, and my R3E was bought on release date, so its 14 months old now. I'm going to keep it and my new CPU + SSD for at least 3 more years, but hopefully more.
Does anyone know if using a 4 pin to 8 pin ATX converter on my second 8 Pin CPU power socket will make my overclock more stable?
http://www.amazon.co.uk/dp/B0051Y0B0...SIN=B0051Y0B0Y
My PSU only has an 8 pin + 4 Pin CPU power connectors, both of which are currently plugged in. Will using this cable to convert the 4 pin to an 8 pin output help at all?
It didn`t give any advantage for me, but core-speed is limited to ~4,2 @ 1,3V running on air.:mad:Quote:

Second that:D
Pushing past 186 BCLK - 188 BCLK and 1884 Mhz ram:
http://img525.imageshack.us/img525/9192/1884.png
At 188 BCLK, I can choose 4.5, or 4.7 Ghz CPU clocks. I havnt tested 4.7 Ghz yet, but I dont think it will fare too well as I get minor instability at 4.66 Ghz.
And for some reason, 190 BCLK and 1900 Mhz ram has never been stable, but I will try again, 189 and 190 BCLK next. The ram is overclocking a bit better than it did on my I7 920 at least, I couldnt get it this high before.
It does around 1700 Mhz @ 6-8-6, and just under 1900 Mhz @ 7-8-7 (maybe more if I had a luckier CPU).
Nice, 189 BCLK and 1894 Mhz Cas 7 ram passed:
http://img848.imageshack.us/img848/285/1894.png
:( And at 190 BCLK I get 'Not exact in round' error right away.
What's your voltage?
I'm pushing 4.3ghz, 205x21 HT off, 1.39v in bios 1.41v cpu-z. 24GB , 3500 QPI/IMC, 1.30v. It's running pretty stable. I had a validation of I think 230bclk on my chip before. Can't seem to find it. I'll be benching my system a crapload before I sell it though :)

@bhavv - How high can you take Uncore?(x2+1)
Seems to be my limit with 24Gb ~1815 7-8-7
Going to X1,5 doesn`t kick it for me, but 2000 8-9-8 12Gb was stable enough for benching
The uncore really depends on your IMC. my chip always likes voltage! I think I broke my own personal record with less than 1.42V with even HT off. I was doing 1.34v ( in bios with QPI LLC ) at 3600mhz with DDR3 1700 at C9 with 24GB.Quote:

I apologize for cross posting this query from other forums ( perhaps I should have jes started here in the first place! )
However I am finding it hard to believe no one has tried to use a 4-way bridge on the REIII considering the ASUS manual states that one should span the second slot for tri sli!
( before one jumps the gun an advises jes to use tri sli or ribbons please read the following: ( and thanks in advance! )
is 4-way sli bridge possible on a 3-way sli?
crossposting from the evga boards:
Originally my manual for my ROG Rampage III Extreme states that correct configuration for 3 way sli ( on the REIII @ least ) was supposed to be:
x16
skip
X8
x8
In which case a 3 way sli bridge will not span that distance.
The new directions given by ASUS on their support forums is..
To use the following configuration instead:
skip
x16( supposedly )
x8
x8
Which is then supposedly fine and does not result in slower speeds.
Not that I do not trust getting x16 from the second slot... however For purely aesthetic reasons:
( My motherboard's EK cooling Block looks better exposed with the first configuration. In fact it's :banana::banana::banana::banana: win with the first configuration )
I would just use the single band sli bridges to span the cards but I have more stable luck with my 3-way sli ( used for dual sli at the moment )
What I would prefer is to span that distance with a 4-way sli bridge if it's possible to use one for 3-way instead.
I am paranoid because the pcb is not quite the same as a 3-way bridges pcb ( while there is solder for every connection on a 3-way bridge the 4-way bridge alternates from one to two connection solder )
Hope that make sense? If not check out the pics:
http://www.evga.com/PRODUCTS/IMAGES/...23-01_LG_8.jpg
vs.
http://www.evga.com/PRODUCTS/IMAGES/...01001_LG_8.jpg
I am hoping someone has used the 4-way sli bridge for a 3-way sli that spans the second slot successfully.
come to think of it...
Does anyone know if all 4-way sli bridges are designed this way? Perhaps there is one with a pcb configured for every connection?
would really prefer not to daisey chain ribbons. but if I have to what would be the right way to configure the ribbons to span the second slot?
I would have thought that in enthusiast forums that a succint "no i tried that and it won't work or yes I tried that and you are good to go!" would be simple enuff.
I think the forums I tried were not as enthusiast centric as I had first thought ( neither am I cuz the price of a quad bridge is a little pricey to simply leave to chance! )
4ghz runs will not be considered for efficiency in the hpc thread.
4.5ghz is the cutoff as previously discussed.
I'm super busy with work right now, but expecting it to calm down once our new release matures a little bit.
:clap: Congratulation! The crown is yours. :yepp: But don't get too comfortable... ;)Quote:

Honestly, if you don't need more than 6 SATAIII ports i'd just put them on the ICH10r because of Intel RST, very useful and neat utility. The marvell will have higher sequential, but the random read writes will be a tad slower than the ICH10R.Quote:

Ok thanks man.
Ok, this is the most 'efficient' I can get mine running:
http://img39.imageshack.us/img39/6629/lowvolts.png
I didnt test the gigaflops yet, just the stability. It will do 4 Ghz on stock voltage of just 1.21v, but just going up to 4.05 Ghz requires around 2.625v, so the perf / volts cuts off and becomes very inefficient over 4 Ghz on my chip.
The voltages might go slightly lower, but the ram is pushed to its absolute limit and wont be stable at less than 1.65v @ 1900 Mhz, just the CPU and QPI might work a bit lower.
I was only pushing it to the extreme when I first got it to test its capability, but this will be my 24/7 setting.
My GTX 560 tis run at 880 / 4600 at the minimum voltage of 0.950v, so everything is nice and cool for daily use, and then I go mad when running benchies :p
bhavv,
you haven't tested any stability there.
run linx for 20 loops with all mem, and then you can call something stable...
Prime doesn't prove anything any more and superpi mod is a performance test, not stability.
I dont have the time to run 20 loops, Its always been fine for me outside of stressing / benchmarking as long as I can get it stable for 15-30 minutes in these stress tests.
I stack prime, linx and super pi to load the system as much as possible in that amount of time, I dont get a single error anywhere else as long as it completes that.
I'd be willing to keep linx running if I could carry on using my browser in the mean time, but that just wont happen.
Just got two of these kits http://www.corsair.com/memory-by-pro...m3a1600c9.html
Anyone know if my GFlops are ok ;
http://img856.imageshack.us/img856/4861/24gblinx.jpg
That ram should work at 1T.
Ive been through two lots of 24 Gb triple channel kits now, and all that they both did was 1600 Mhz cas 9, or 1800 Mhz cas 10, so boring and slow compared to 2 Gb sticks.
bhavv, with 5120MB memory size in Linx and 4.5ghz, it should take less than an hour to do 20 loops. Do it when you're watching tv, or when you eat dinner or something. It's not long at all.Quote:

So in short, running all of them together is WORSE stress testing than running a single one by itself.
At that problem size, your GFlops are fine. However, you're not fully stressing your CPU. Drop your problem size to 9216MB and re-test. You should be hitting 70+Gflops.Quote:

How many sticks are you running? and what is your uncore/IMC freq? 1.35v is honestly unnecessary, I only need that much with 6x4GB at 1700 with uncore at 3600, and I'm sure I can even drop that down a notch.Quote:

Guys,
I am on 1301 BIOS, and I have Core i7 920@4.25Ghz, should I update to 1502 ?
I know this post is useless now but I just had to point this out for the future.
Microcenter was selling the R3E for $191.99 and R3BE for $367.99. Did anyone know about this? Of course they are ALL sold out now. FMLLLL :mad:
I've made a rather significant discovery and thought I might share my findings. Seeing how many people have memory overclocking issues I'm hoping this may help.
I have recently began fiddling with DRAM Ref Voltages. I have actually always set them to +0mV without completely knowing what it is. After learning what they are, and after learning that R3E sets the proper DRAM REF Voltage on Auto (1/2 of VDIMM voltage), I was using the AUTO setting. After being unable to stabilize certain overclocks, and playing with and exhausting every voltage, memory timing and clock skew settings, I decided to give some thought to DRAM REF Voltages.
Okay so basically my R3E overvolts all parameters by about .012v-.013v. CPU PLL set at 1.788v will run around 1.8v. VDIMM at 1.616v will run around 1.628v. IOH at 1.126v will be around 1.139v. So I'm assuming DDR REF Voltage is being overvolted by about the same amount. So if my VDIMM is set at 1.616v and Ref voltages at Auto, then according to the way the R3E Bios sets Ref voltages, it will be 'half' of VDIMM voltage. In this case, it will theoretically be ~.808v.
If my board overvolts every parameter by about .012v, then my Ref voltages are being set at ~.821v. If Rev voltage should be half of VDIMM, then .814v is required for 1.628v VDIMM. I have to decrease the Auto Ref Voltage of .821v by .007v. DRAM REF Voltages have smaller increments when going negative (-2.5mV) than when going positive (+12.5mV). So setting Ref voltages to -2.5mV or -.0025v makes my hypothetical Ref voltage .8185v (.8185v*2 = 1.632v). Still too much for the voltage my memory runs at. So I set my Ref voltages to -7.5mV or .0075v, making my hypothetical Ref voltage .8135v (.8135v*2 = 1.627v). This made a day and night difference for me. More so than adjusting any other parameter in the BIOS.
In regards to VCore, with my Ref voltages at AUTO and running 4.187GHz, I would pass 5 loops of LinX at 1.25v (~83GFlops), 20 loops at 1.25625v (~82GFlops), then only 3 loops at 1.2625v (~82.8GFlops). Only after finally finding the right DRAM REF Voltage setting, it passed all 25 loops at 1.25v (~84GFlops). I might try to take VCore, VTT, and VDIMM even lower now :p:.
It's late and I'm tired so hopefully what I just said makes sense. I would suggest R3E owners to get a hold of a voltmeter and test how much their boards overvolt. Play with DRAM REF Voltages to see if you gain stability.

Hi, this is the ram I use:Quote:

They are crazy clockers at CL 7 in dual channel / P55 / 1.65v, but not so good on X58. But they are still better than any triple channel kit I've seen (in the UK at least).
At 158 BCLK and 951 Mhz (1902 DDR), it needs 1.65v DRAM and 1.35v QPI. If I set the QPI to 1.3375v, I get immediate BSODs within 5-10 minutes of stress testing.
I just managed to get it working stable with no errors at 190 BCLK and 952.5 Mhz (only 1 Mhz higher, but previously it wouldnt work, it seems to gotten burned in). This takes 1.3875v QPI, and 1.67v Dram, which I have read is fine to go just one setting above 1.65v on the DRAM on X58.
Loosening the timings above 7-8-7-24 does nothing to improve stability over 1900 Mhz. Going just 1 BCLK higher than 1905 Mhz ram = only 8 Gb ram detected and errors.
I managed to boot with 12 Gb ram detected and complete super PI 32m with 1925 Mhz cas 7 ram, but it took 1.7v DRAM which is too much extra for too little gain. 1900 Mhz is the max it will do at 1.65v on X58.
190 BCLK and 1905 Mhz 7-8-7-24 ram is the current best I can get everything to. I have the CPU running at stock volts and a 21x multi for 4 Ghz now for everyday use, plus the CO voltage and clock reducing thing active which reduces the multi down to 12x while I'm not playing games :)
My 6x4 Gb sticks ran fine at 1800 Mhz cas 10 with just 1.275v QPI, but those crappy modules arent comparable to these geil ultras. I've abandoned hope on looking for performance 4 Gb modules now, I just cant find any and have been through two lots of 6x4 Gb (Corsair Vengeance and G Skill ripjaws, both had identical lame ram chips - Cas 9 1600 or Cas 10 1800).
Also, I was consumed by madness, and bought a new SSD to replace my Raid 0 gaming drive:
http://img46.imageshack.us/img46/9716/dsc00269vc.jpg
Thats my graphics card budget gone oopsie, now I have to wait until 2013 and the 28 nm refresh gfx cards before more upgrades. I think I'll save towards a second 512 Gb M4 and new graphics cards in 18 months time.
Nice cooler you took in you`re madness. :ROTF:
What fans are you using on them?
Just the fans it came with, plus a Xigmatec red led fan as a third:
http://www.overclockers.co.uk/showpr...odid=FG-002-XG
I have 5 of those fans in total, they push a lot of air and are completely silent (2x intakes, 2x exhausts, 1 on the Phanteks cooler plus the two Phanteks fans).
Ok, after reading that thread about my ram again, I decided to copy the timings that others were using:
http://img545.imageshack.us/img545/6996/burnedin.png
The ram is beginning to get more and more 'burned in', prior to running it at 1866 Mhz Cas 7, it would NEVER run stable at this current setting, even with 1.4v QPI and more DRAM voltage!
Right now its going up to 1933 Mhz but requires 1.696v for that, this is too much for X58 right? I tested 1933 Mhz once and it completed super pi 32m with all 12 Gb detected, this was never possible before!
... My ram isnt going to die is it?
Using DMM, my R3BE gives, using 24Gb:
Vdimm set: 1,65625V vs. DMM Vdimm 1,644
Vdimm set: 1,68275V vs. DMM 1,673V (Didn`t give any gain, though)
Vcore set: 1,275V 100% LLC vs. DMM Vcore: 1,268~1,281V during LinX, or Prime95. Spike up is seen, when running LinX, at the end of a run, going to the next.
CPU PLL set to 1,65625 :D
12V Silverstone Idle: 12,04V vs Load: 11,99
Same variation on the other lines.
New core, first 4500 run:D
http://valid.canardpc.com/show_oc.php?id=2156358
Linx and 3DVantage/11 stable
Nice run, very good chip you got there! What Batch is it? So it was just a weak IMC on the last one huh? Very impressive 24GB run :up:
Batch I have to look up.:shrug:
IMC seems to be a little less than the Xeons, both can do +1800, both core`s limited to ~4,2. (On air that is)
The X990 has a better core, 4,5@1,3V-100%LLC (6C-6T)- DMM 1,32V - 4,3@1,3V-100%LLC (6C-12T)- DMM1,34V :rolleyes:
Still tuning, and hoping for more.......
That's not bad at least the Core is better on the 990X.
I would suggest using 50% LLC on CPU and no LLC on QPI. From my knowledge and experience it seems Intel architecture is designed to have fluctuations in voltage. You may be more successful with your overclock so give it a try. Also since you are running 24GB, I would mess with DRAM Ref voltages. I recently learned increasing it helps also, so try +12.5mV on all channels data & ctrl.
Every single one of my chips has done better with LLC at 100% and QPI LLC enabled.Quote:

Sure if you are setting the same voltage in BIOS that makes sense as the 'real' voltage with no droop will be higher hence higher clocks. I think Spoolin was saying that if you compensate for that droop in BIOS but setting the voltage higher and have 50% LLC and Vtt LLC off is that the result is less electrical noise on each load line and the result of this cleaner power plane is often slightly higher clocks at the same real voltage.

Nice work :up:
I know we have all spent hours testing, but I have never seen 50%LLC with additional overvolting to meet the minimum voltage requirement do better than 100% LLC. Maybe it's a chip to chip thing... But I've tested so many chips that I find it hard to believe.Quote:

That's exactly what I was getting at. Just needed a engineer level explanation. Thanks :up:Quote:

I know the downside is higher voltage at idle, but it's worth it to achieve certain overclocks.
I think those who have not tried should give it a shot. Looking forward to seeing your guys' results.
P.S. Zoson - I wish I can convince everyone out there who buys fans to choose Gentle Typhoons. Have you ever used them before? Great choice I must say, as I use the same myself. I have to say they are by far THE BEST fans I've ever used. Before realizing my 920 was just a high heat leakage chip I went through so many different fans. GTs excel in sound, static pressure, and quality. When you see them in person you can tell they are 'real' fans, what fans are supposed to be. All other fans you have used up until now will seem like toy fans. You'll see ;).
Very nice indeed! Let's see some Vantage or SPI32M runs :) (or even LinX if you dare)Quote:

Gentle Typhoons are AMAZING. Take it from someone who has tried all the other good fans. GT's are hands down the best. Skinnee said that the YL D12SH were in the same class... But they are not even close. NOT EVEN CLOSE.
If you are looking for new fans... Don't go cheap... GET GT's AND YOU WON'T REGRET IT!!!! I'm so happy.

I've forgotten how nice it is to see all these voltages on desktop. Even if they aren't 100% accurate, it's sure better than nothing LOL.
Put 1502 on BIOS1 and 0003 on BIOS2.Quote:

Better late than never hey Lenny ;) I run 0003 24/7
Heh :D I'll have a look at 0003. I've got 1502 on my pen drive ready for flashing but seeing that the board came with 0901 on #1 and 1102 on #2 I thought I'd have a play and get familiar with the BIOS without going in too deep. 0901 sucked... couldn't even POST at 188x25; but 1101 was perfect and I've been able to do some amazing benching with it.
Managed to get 18126 on Geekbench with 5GHz (151x33) using 4240 uncore and 2120 memory (8-9-8-24-88-2T), with 1.425 VTT and 1.525 vcore. 1.4125 VTT was just a little too low and I got a blue screen about halfway into the test...
Compared to the P6X58D-E the voltage behaviour of the R3E is VERY different - it really jumps about under load with LLC at 100% and overshoots the BIOS value by a considerable margin, which I didn't expect; and the fluctuation under load is really bad, going from 1.434-1.456 in LinX - my other board was rock solid under load, never changing in CPU-Z. I'm not quite sure how to access certain BIOS options, eg QPI LLC, which is greyed out near the top of the tweaker menu... but that will come later.
In any case I'm very happy with the board but, unfortunately, my GFlops problem (peculiar to LinX, interestingly) has returned - getting a good 10 GFlops lower than I should be and it's REALLY annoying, because I just managed to sort it out on the other board. I've already got a 4.7GHz HT notch on my LinX belt but the memory and uncore were low so GFlops are only at 86... I did get one amazing run with 89 GFlops consistently but it crapped out on loop 20 :rofl: (you just have to laugh at the irony).
This time round I'm completely flummoxed. At least the last time the problem presented itself in other software, eg low Everest and Sandra memory bandwidth... but this time everything checks out (including Geekbench, which is what alerted me to the poor memory performance in the first place).
I've left all CPU features enabled, as before, and in addition to that I've enabled C-States for the extra bandwidth, but no change. Will give BIOS 1502 and 0003 a go tomorrow and see how they check out, and then I can play around with PLL and LLC and see what I can do with 4.7GHz HT. :up:
OK I flashed #1 to 1502 and at reboot I got a "bad bios checksum" error... put the CD back in and now it's back to 0401.
Tentatively flashed #2 to 0003 and to my surprise it worked first time and I'm using it now. I'll try reflashing #1 to 1502 again and hope for the best.
EDIT: just tried 1502 a second time and it worked, so now I have two good BIOS versions to play with. Cheers guys. :up:
NP you'll figure it out. QPI LLC you need to enable a jumper on the mobo then you can use it. I just leave it off though.
Ah thanks Cryptik - I'll just leave it off at the moment. Any idea how much QPI/VTT undervolts/overvolts compared to BIOS value, or does it vary between boards? The board is a bit on the big side for my case (damned Asus calling it "ATX"...) so I can't access the voltage measure points but I'm really keen to get DMM voltage readings so I'll try to work something out there. As far as stability overclocking goes, I'll give 0003 a try first. :up:
So I stuck with 1502 (for the moment) and decided to do a bit of relatively tame IMC testing with 3200MHz uncore and 1600MHz 6-7-6-18-60-2T mem and I gotta say it's been a royal pain in the butt trying to get it stable with this board - it's taken me about six hours of repeatedly coming back to a "red" LinX because QPI/VTT wasn't high enough. I'm used to setting 1.275-1.3v on my P6X58D-E, but oh no, this board has different ideas.
I got some really sweet runs (even though they did crap out) - check the consistency of GFlops here:
QPI/VTT: 1.325 (BIOS), 1.28 under load in HW Monitor
(Diagnostic mode, pagefile disabled)
http://img560.imageshack.us/img560/7537/4ghzerr2.png
Part of me thinks that LinX is just tormenting me, because it knows how much I loathe it. :rofl:
And now onto my first successful run with 20 passes. Given the consistency of the above run, I have NO EARTHLY IDEA why GFlops fluctuated so much in the only run that actually passed. The first time I started LinX I got 49 GFlops on the first pass... so I just closed it immediately and fired it up again without rebooting. Like I said, it hates me lol.
QPI/VTT: 1.35 (BIOS), 1.30 under load in HW Monitor
http://img843.imageshack.us/img843/9260/4ghz.png
One thing's for sure: the DMM is coming out tomorrow. Cryptik, any reason why you don't use QPI LLC? There's no way I'm leaving it disabled if droop is as much as 50mV.
I'm also really confused because I was able to bench 4240MHz uncore with 2120MHz C8 memory (at 5GHz no less) with "only" 1.425 VTT in BIOS, which means it was getting about 1.375 under load... yet it wants 1.3v for a measly 3200mhz in LinX?
But I'm definitely not complaining, coming from an i7 920 that needed 1.4 VTT for 3200MHz :down:
Edit: I think 1.3375 (bios) is as low as I'll get VTT without LLC for 3200MHz with tight memory. Not sure if a higher QPI Link freq would need more QPI volts or give better performance, but I left it on "Auto" in BIOS (mostly out of negligence tbh). CPU is at 1.2000 in BIOS and was 1.197-1.204 in CPUZ; Northbridge actively cooled by two silent 120mm fans stacked, which dropped its temp by a good 15C.
Still getting weird GFlop spikes but at least this time it all stayed within 1 GFlop of 77 :up:
CPU: 1.2000
QPI/VTT: 1.3375
http://img545.imageshack.us/img545/9017/4ghzt2.png
Just did some BIOS/software/DMM comparisons and the results are interesting, especially with QPI/VTT.
http://img52.imageshack.us/img52/9178/dmmtesting.png
First and foremost I'm surprised by the innacuracy of the software voltage readout - there was A LOT of vcore fluctuation in CPUZ during LinX testing, from 1.197v spiking as high as 1.224v sporadically. With the DMM the vcore remained solidly on 1.187v throughout, dropping to 1.184v near the end of each loop.
As for QPI/VTT, the actual load value is nearly 60mV lower than the BIOS value, which explains why I could set VTT so low on my previous board. Vdroop aside, vdrop alone is particuarly bad at almost 35mV, compared to only 16mV on the vcore. RAM is a solid 21mV below BIOS value and didn't fluctuate during testing. Impressive. :up:
I'll test QPI/VTT again with LLC enabled and see how I get on. If you guys have a DMM handy and haven't already tried it, I'd suggest giving it a go as the real voltage values can be quite different from what BIOS or software tell you. Cryptik - your 4.5GHz 1.33v submission might be as low as 1.31v under load :shocked: :D
I use qpi llc and 100% calibration on the cpu. I have never seen a situation that it helps to have them off/lower, personally.
As of now I will also be using both. :) I did more DMM testing with QPI LLC enabled and with 1.3000 set in bios, vdrop is only 9mV and vdroop a further 7mV, so 1.284 under load. Brilliant.
And I actually love this board so much. I re-ran my 4.7GHz HT LinX run and it was going good at 90 GFlops until about 20 mins. All I needed to do was lower CPU PLL to 1.7v and it passed with flying colours. Tried enabling C-States for the extra bandwidth but LinX was having none of it, so I just left them off. Measured CPU, QPI and RAM with the multimeter. BIOS values were 1.45, 1.36875, and 1.67 respectively.
4.7GHz HT (142x33), C-states disabled BIOS 1502
CPU: 1.437 real
PLL: 1.7
VTT: 1.352 real
RAM: 1.64 real
All other voltages stock
