It really is starting to look like Newcastles are the way to go at the mo.
I'm going to put my winnie on LS this evening with neo2. Pray to the overclock Gods for me. I am going to Jinu's apt. tonight to try my cpu out on his neo2 and LS, just to make sure my board is the reason I am having so many problems. Hopefully the gods will be in a good mood and the overclock will be prosperous.
if only OcUK were on time id have a cpu right now as ebuyer came to pick up the other chip alreadyQuote:

If I do not gain a single MHz with any of the other BIOS releases, I'll conclude that the above configuration is final and will then commence testing to discover the lowest voltages I can run for CPU and memory while remaining stable and error-free.
The Bottom Line: I'm a happy camper with my Newcastle 3500+. :D

Conrad, are you online bro?
Let me know within 30 mins if you are and I will email a screeny to ya if that's cool... you'll love this one ;)
PS, that 1MB SuperPI is for that clock... I havent kept up with all this but seems the DualChannel really makes a diff in SuperPI. With a loose 10x260 I get 33s and with a tight 10x256 I sometimes get 33s-34s.
Note to ALL:
I have found that when I had my Trc-Trfc @ 15/17 I could clock higher with just 3.2v... eg, 256-257 was the limit... now that I have tightened those timings to 11-15 and also reduced a few others I am having to run 3.3v at 10x256. Still great memory, but keep that in mind when "pushing for max"... Trc & Trfc are biggies ;)
Very nice oc there conrad :thumbsup:Quote:

Very good observation on the TRC/TRFC. You just beat me to posting the same thing. On My DFI NF2 board The default is 13-15. I usually lower it to 12-14 as that played nice with my BH-6 and also gained me slightly higher 3dmark01 scores. Earlier today in desperation I figured I would raise those two values back to default (13-15) as it was about the only thing left to try before I gave up trying to get any higher on this memory. After raising those I was able to go one mhz higher on my fsb with fewer errors than before. Not a massive difference as you have also noticed but still something to keep in mind.Quote:

Well. I seemed to have isolated the problem and I just might be able to find my missing megahertz...all 265 of them...and hopefully more. My problem is heat - a lot of heat. I removed the 92mm Sunon that was cooling my DDR Booster and VX modules and replaced it with a 120mm Sanyo Denki DC San Ace (Model 109E1212H101). I also cut some heavy duty cardboard and made a wall to channel all of the air solely on the DIMM region. What did I gain? So far, 3MHz. :D

I plugged my CompuNurse Digital Thermometer to the edge of my CPU. The temperature while running Memtest and Super PI was a killer 68C!!! If I still had my Thermalright SLK-948U to play with, I'm positive I can keep the CPU and memory controller cool enough to push for more.
Time to test 10x263MHz.
:toast:
Congrats Conrad... 263 is a REAL nice clock dude. Try setting Trc=15 Trfc=17... you will lose a little bit of performance but you may gain 2MHz-4MHz ;)
Take care of the CPU too... looks like a keeper :toast:
And biggy thanks for hosting too bro, I will post my screenies in a sec
The above shots are 10x261MHz. I'll test 10x263MHz after I grab a bite to eat. I'm starving from all of this testing. :slobber:
Awesome news! I suspect heat is an issue with lots of people running this memory. Even at 3.3v, with a strong enough fan this stuff gets quite warm to the touch. Even just putting your hand in the general area of the dimms has you feeling the heat that is being radiated from the sticks. I can only imagine 3.6v with a booster that is known to get quite hot to begin with.
These are with 3.4v set in BIOS but as soon as ANY sort of memory load comes into play it quickly drops to 3.31v-3.35v and jumps round there... so effectively it's only 3.31v seeing as the weakest point is what counts.
9x270 2-2-2-10-1T 1x512MB OCZ VX - Sisoft Sandra Memory Bandwidth
9x270 2-2-2-10-1T 1x512MB OCZ VX - 3Dmark01
This one can sit at windows all day but benchies die as soon as load is put on the memory... I NEEEEED a 3.3v rail mod but no way in heill do I want to kill this PSU... we'll see... hehehehe

Good job, Alex. What's your maximum Super PI 32M stable with just one stick? I think I'll start playing with single channel after I get a result with Hexus Pifast and complete a full Super PI marathon.
http://webpages.charter.net/conrad-d.../263sandra.png
http://webpages.charter.net/conrad-d...263everest.png
If I can get through Super PI 16M and 32M at 263MHz, it'll be a miracle. Memtest was at 70C while I was testing memory at this speed. Even though 28 loops ran without error, I think I've reached the absolute maximum heat my CPU will tolerate and an increase of just 1C will probably cause Super PI to error out. There's only one way to find out. ;)
CPU temperature fluctuated between 71C and 72C. Amazingly, I pulled off the Super PI and Hexus Pifast runs, but I'm not going to be running with these temperatures on a daily basis. I'll resume dual channel testing again when I receive my phase change creation from chilly1.
http://webpages.charter.net/conrad-d...263pitests.png
fook me your doing well conrad :)
Off topic mode on but still related to A64's------
one thing i have noticed with A64's tho is a wierd 30 second delay in windows for all the drivers to laod, some open straight away but others lag, after 30 seconds it will be fine
it did this on the 3200winchester and 3500 newcastle i had before (tried reinsatlling XP, same problem), it appears the chip is fine when you first stick it in but after a day or this delay kicks in (cpu is 0% for this 30seconds btw)
The chip i stuck in today, my new 3500 turned up (NC) doesnt have this pause at all and is super silky, im guessing i may have damaged the mem controllers with too much voltage on the others, as i have a tendancy to chuck volts in them within the first few mins, not letting them burn in long enough to get a rough idea of how they clock??
With this cpu im not going over 1.65v for a few days, to see if this silky performance remains and i dont get the dreaded 30 second wait!!
Off topic mode off ------
edit: this has only been on 939 with the same msi neo 2 btw
guys y havent none of u who have the vx mem tried 2.5,3,3,6 timings to see how far they ll go???? i d interested to see the max fsb at these timings! Cheers :D
i think its been said that it prob wont scale much higher with slacker timings but i guess the only way to find out is to test themQuote:

http://webpages.charter.net/conrad-d...X/263prime.png
conrad, what temps are you getting and what are you using to cool your system?
71C on the CPU side under Prime Torture Test. I'm using the AMD retail-boxed HSF. The VX modules and DDR Booster should be pretty cool since I employed a 120mm fan along with a wind tunnel to isolate the air in the DIMM region.
I'm not going to run my CPU at 10x263MHz because the temps are so high. I just wanted to see if 2630MHz would still be stable with insane heat.
EDIT:
I just noticed that Memtest recognizes my Newcastle as an .09 process chip.
very well done. I think you have one of the best pairs of those sticks that I've seen. What volts did you need at 263 and have you been doing a lot of burning in to get that stable?
3.51VDIMM measured with a digital multimeter. Any more voltage than this will cause errors. I'm pretty sure there's a little bit more to be gained from the VX modules, but at this point, the CPU is running way too hot. I've seen 265MHz 2-2-2-10 on my 3000+ Winchester, so I know that the VX definitely has potential. I've been burning these modules with high voltage since the day I received them. And I was among the first batch of people to order them from excaliberPC on November 30th.
I'm now tempted to purchase a Thermalright SLK-948U to mate with a 92mm Vantec Tornado that I have in my storage bin. But since I'll be moving up to phase change, it might be a better idea to just wait. I'm fairly unpredictable and react on impulse when it comes to purchases and acquisitions so you never know. ;)
I have a feeling my RAM will do 270MHz 2-2-2-10 in dual channel with phase change. We'll wait another month and see.
EDIT:
Mtemel and BAcon - I have tested with slacker timings. I get errors the moment I change a value of 2 to 2.5, 3, or 4. I only tested with high voltage but I'm fairly confident that if I were to drop the VDIMM a few notches, I can run 2.5-3-3-10. I'll test later when I have a chance. I'm also going to test the following to see what performs better at DDR400 using 2-2-2-10 in 1:1 dual channel.
11x200MHz | 2-2-2-10 | OCZ VX
11x200MHz | 2-2-2-10 | OCZ 3200 Platinum Deuce
http://webpages.charter.net/conrad-d...NandTUNNEL.jpg
Forgive the illustration because I'm in a hurry and my digital camera seems to have conked out on me. :( Anyway, this is just to give you an idea of what type of cooling I am using for my DIMM region. This crude but simple modification allowed my VX a net increase of 5MHz (from 258MHz to 263MHz), which was stable enough to run many loops of Memtest, Super PI all the way to 32M, and just over 12 hours of Prime Torture Test Blend Priority 10.
If you're looking for a few extra megahertz from your VX, you have a fairly good chance of unveiling them with improved cooling.
Now please post up a rock-solid, stable, and error-free 270MHz in dual channel 2-2-2. I know someone out there has a lucky set.

I'm confident there's more to be realized if I can control the temperatures. If the CPU is hot, so is the memory controller. If the memory controller is running way too hot, the chances are you're not getting the most out of your RAM.
Awesome idea. The heat being blown out from the heatsink hits the ram directly, so this wind tunnel concept is a great way to keep that heat off the sticks, and actually deliver cooler air to them!Quote:

How do you fix the tunnel to the board?
On another note... I've been fiddling with more timings last night and found a few more interesting bits of info...
1) I can run my modules as tight as 1T-1.5-2-0-2-7-15 (CPC-CAS-Trcd-Tras-Trp-Trc-Trfc)... but cant drop my Trfc any further. I usually see people running Trc & Trfc within 2-4 of each other but 15 is the lowest I can get Trfc, whereas Trc goes to the lowest setting of 7 with no problems.
What is everyone else running?
Maybe it's my memcontroller.... these settings are stable up to 260 w/ 3.3vDimm (my max vDimm for now).
2)Tref is a biggy!
I only ran the settings that related to 200MHz (1:1) ratio... but here are my results with the settings I tried (CPU @ 10x256):
3120 : A close 2nd. Sandra bandwidth = 397x/397x , SuperPI 1MB = 33s-34s
0064 : No POST
1560 : 3rd best. Sandra bandwidth = 393x/393x , SuperPI 1MB = 34s
0032 : Horrendous Bandwidth!!! Sandra bandwidth = 500/500 , SuperPI 1MB = 1:02 m
0780 : 4th best. Sandra bandwidth = 381x/381x , SuperPI 1MB = 34s
0016 : No POST
3072 : Best for me. Sandra bandwidth = 397x/397x , SuperPI 1MB = 33s
0128 : Sandra bandwidth = 252x/252x , SuperPI 1MB = 35s
get that camera working soon, this I gotta see.
Didn't have time to do many 32mb runs or fiddle with multis today but here's my experience with SuperPI 1MB with my one better stick (does bout 1-2MHz better than the other)... you're hosting these so it's old news! but act interested heheheQuote:

Thanks again to Conrad for his generous hosting
10x270 1.5-2-2-0-7-15 SuperPI 1x512 OCZ VX
10x269 1.5-2-2-0-7-15 SuperPI 1x512 OCZ VX
10x267 1.5-2-2-0-7-15 SuperPI 1x512 OCZ VX
10x265 1.5-2-2-0-7-15 SuperPI 1x512 OCZ VX
10x263 1.5-2-2-0-7-15 SuperPI 1x512 OCZ VX
[Edit] I have a feeling 10x271 would give occasional 31s and 10x272 would give consistent 31s... but my CPU is getting maxed there.
I ran 10x271 once and got 32s but it was close... and then it rebooted... I think more VCore would stabilise it enough for more runs tho.
Make that 2. :cool:Quote:

What timings you running Conrad? I've done a fair bit of testing with regard to timings lately... wouldn't mind comparing some info
you think i could get 240 @ 2-2-2-10 1T at 3.2V or less?
if you ask me TCCD much better then this VX....same price
VX+BOOSTER = 280$
TCCD = from 221 to 350$...depends

The timings I used for 10x263MHz 1:1 1T 2-2-2-10 are all listed here. This is 100% rock-solid and Prime Torture Test stable. I can run any CPU and memory intensive application without incident. ;)Quote:

I'm not sure bout your Tref "value" but I think that is it... I got it from here
Those are my 260 3.3v timings, 100% stable... but for more MHz I think I really need more voltage.
How low can you get your Trfc dude? Mine is seriously unstable below 15, but strange thing is Trc will go down to 7 no problem.
I did a write-up here @ DFI-Street about my timings and what I've found to be the best so far... I think you'll find some of it interesting :)
I just wanted to make sure that we all are up on the subject of some A64 90nm CPU's earlier than week 41 failing Prime95.
The Official thread is here: http://www.xtremesystems.org/forums/...962#post631962
I won't go into details here, but please if you are using Prime95 to test while running an A64 Winchester 90nm take a minute to read this. Many CPU's fail at stock settings. Always test at BIOS defaults for 7+ hours before using Prime95.
Thanks
260 Mhz @ 1.5-2-2-0..... *faints*
Anyone have results from an intel chipset? (875) I'd really like to pick up a set of these...
The DFI 754 board definitely has more options as far as memory timings are concerned. This is one thing that I truly miss most about that board. I do not know what my Twcl value is at, but Drive Strength is at Weak in BIOS. The only two options available on the MSI K8N Neo2 Platinum are Normal and Weak.
Anyway, the values I have on that screenshot are the absolute tightest timings that I can run 100% stable. I can slacken up the numbers a bit to gain 1MHz or 2MHz, but I am not willing to sacrifice performance. Setting CAS Latency to 1.5 yielded no increase in Sandra bandwidth, no decrease in Everest latency, and no decrease in Super PI 32M when I tested.
I finished the rough version of my wind tunnel this morning. I'll cut up three more pieces of acrylic tomorrow and start on the final version. I have other projects that need tending to, so it'll probably be another week before I have everything complete and ready to install.
Cheers!

Also my case it a bit cramped, so airflow ain't great, might leave it with side off. I have a XP-120 so it blows a fair bit onto the memory, might not bother cooling them, might not have to if i can't put much voltage in hehe.
10x230 3.1vdimm is ok, goa have to test it better.
Whats best to test memory stabilty? Prime or memtest or 3dmark?
can you run 230 at 3.1v? Specs state 3.2 is needed to stabilize 2-2-2 timings.
240 at 3.1 passed mem test once, lol.
Ive have to test more tomorrow. :cool:
PC3200 Platinum Rev2 is also only warranted up to 200 2-2-2.... OCZ almost always stick to the cautious side when rating their modules.Quote:

Off the top of my head, I do not know. I just recall 2.85VDIMM for 230MHz because that was all I had to play with when I was waiting for my DDR Booster's replacement. I'm at 3.51VDIMM right now and to test maximum frequency at 3.2V, 3.3V, and 3.4V would be a pain for me...hahaha. Sorry, Alex. I'm pretty lazy today. :D
If your PSU has solid rails and you don't wish to perform any mods to the rails, you can always pick up a DDR Booster (or just wait for the HiPro unit).
My PSU is PC P&C 510w Deluxe... I think she has a fair bit of grunt, but it was too expensive to mess with. Although I would happily swap it for a 520w OCZ PowerStream... or 600w if possible.
I dont want a Booster... IN MY OPINION, they are too unreliable and not necessary when you hav a motherboard capable of massive VDimm... I jus need a higher 3.3v rail I guess.
Anyone have experience with modding the PC P&C... jus in case I get game? hehehe
[EDIT] what is HiPro's unit like?

So I have gotten 260x10 so far at 3.4v Not to bad I must say!;)

I am pretty sure this RAM will go higher that 260 with 3.3v-3.4v but my CPU is getting tired at those speeds by the looks.
Yes. I initially had my VCORE at 1.550V + 5% to stabilize my memory at 257MHz. Everything I posted from 258MHz all the way to 263MHz required 1.550V + 10%. At that point, I stopped adjusting VCORE because my CPU temps were above 70C at load.
My buddy, ronacevedo, is willing to lend me his cascade until I order my system from chilly1. I'm currently considering his offer to see how much more I can do with improved cooling.
What are average newcastle idle and load temps... Or more importantly, whats the max SAFE temp?
depends on vCore, the more vCore the lower the max temp... that is why all mobiles are rated at a higher temp.Quote:

I then tested at 275 HTT and 166 memory buss selection for 225mhz on VX. 2-2-2-10 1t, 3.3v and it errored in memetest.
Next I set 2.5-3-3-10 1t with the same settings as above and there were errors.
So, I grabbed the only thing I have that will take the voltage, good old OCZ BH5 2 x 256 and it worked fine at those last settings.
Now I'm wondering if the errors are due to running 2 x 512mb. So......I load up OCZ TCCD 2 x 512mb at the same settings, but lower voltage of course......and TCCD works fine with the dividers.
Now, truthfully I can't see any benefit running A64 with a divider. The CPU is not FSB limited like an Intel. There are aslo some unusual timing issues that come up when using dividers on the on die memory controller. I believe this is what the issue is here. It may possibly be a BIOS or chipset related issue that shows up when pushing the VX. Any theories? Anyone have other memory that dosen't like dividers?
Looks like im stable at 250 2-2-2-10 3.5v

Andy - The reason why I show interest in the memory dividers is because I would like to push my CPU a little bit further. For example, what are my options when I want to run a CPU multiplier of 10 and an HTT of 316MHz, but my RAM maxes out at 263MHz? The 166MHz option in BIOS would be perfect to get my memory down to the target of 263MHz, but selecting this option causes the system to hang. I'll be borrowing my buddy's two-stage cascade for some testing, but I see that with my 3500+, I'll be limited to running 11x263MHz if I must insist on using the VX modules.
So now the question is: BIOS issue or NF3 issue? I can run dividers with my Platinum Deuces, which is what led me to question the VX modules as being the problem.
Thanks conrad :)
.... btw what is your vcore and booster voltage at 260 2-2-2-10?
I had the VX for a few days in my P4 while waiting to get a new NEO2. On my AI7, it ran perfectly fine at 220Mhz 2-2-2-5 3.2v 1:1 but when I tried to run at at 275Mhz 5:4 which should give me 220Mhz memory, the PC won't even boot. Didn't do any further testing though.Quote:

Back to the VX and NEO2, I picked up a new board yesterday and only had time to install it a few hours ago. The ram is now at 255Mhz 2-2-2-10 3.43v (multimeter) and just crossed the 2 hour mark of memtest test #5 :banana:
awesome! Let's see if 260+ is in store for you.
VCORE - 1.550V + 10% BIOS
VDIMM - 3.51V Digital Multimeter
WOW! that's lower than DDRII :) heheheheQuote:

My fingers were overclocked and produced errors on that post. ;) I've edited it to reflect 3.51VDIMM.
I said it to you in my e-mail and I'll say it to you again: I think you've got the best set of VX around. Socket 939 and maybe a little bit more voltage should really make those puppies shine.
:toast:
Yes, quite impressve stuff.
Without a booster it seems to be stable at 240 10-2-2-2 with only 3.1vdimm. Gonna get a booster after me xmas holiday. Shootin for 10x260. :p:

Honestly I dunno what the cause is. I see your point about the super cooling. Looks like you need an FX55 or to use the 3200 II until we figure it out. Just kidding about the FX55, but the 4000+ I have now is really nice. It appears it share the same cache and core size as the FX55, but runs at FX53 speeds stock.Quote:

I bought 2 pairs of VX. (so 4 sticks of 512mb)
Now, they do come matched in good way or bad way in this case...
From best to worst. All test done @ 3.5v. Will test the bottom 2 duds at 3.2v and 2.6v to see if they even work @ guranteed timing. Memtested on #5 for 30 loops each as I wanted to get preliminary feeling quick.
267 2-2-2-10 (!!!!)
255 2-2-2-10 -> Not bad at all.
225 2-2-2-10 -> errr.... @ 3.5v?
-200 -> couldn't do 200... this one will get through testing done and probably will be RMA'd as well as 225 one that is... just... (I bet it will fail stock volt/timing test considering how poor it did with 3.5v)
Can we say.... I've just covered about whole spectrum of below 200 to top end of VX with only 4 sticks?... I really think there should be some more consistent result...
jinu117,
Sorry you seem to always have bad luck. We do appreciate your loyalty and will look after you. RMA those 2 sticks and the guys will test them. I am interested in knowing what the "duds" will do on out test rig.
Thanks
Who knows... :) Just tested one of the duds on 2.6v 2-3-3-8 and failed.... running memtest 7... (hmmm not 5... strange) in the mean time the better 2 are running in pair in dual channel @ 250 no sweat right now. Wonder if I will actually get 254 dual channel :)
Mem runs warm (probably around 30c-32c) @ 3.2v but at 3.5v it is hot as in 45-50c with 2 80mm fan blowing on it. How hot are yours for those who run 3.5v?
Yeah it must be my curse... either i get something exceptional from OCZ or something that doesn't even do stock well. Well, the silver lining is that I do get few exceptional things here and there I guess :P
Don't feel bad Jinu... I have had horrible luck the past year. Very weak chipsets on my motherboard, a mobile Athlon that can't even do 2.5ghz, an X800 that has flashing textures all the time and ram that won't clock anywhere near what others are getting with the same stuff. It sucks I know. To top that off I had 2 psu's blow on me and a dvd burner that decided it didn't want to burn anymore. bah.
With 3.43v, my VX is 10 hours memtest Test#5 stable at 255Mhz 2-2-2-10 but failed Prime95 Blend Test and SuperPi 32M no matter what I do. I already tried increasing the vocre and use lower multiplier and the result is still the same. I can only complete 32M SuperPi at 240Mhz. Is there anything else I should change?
edit: woops my bad
blinky - That looks more like 2x256MB to me. My questions always revolve around stability. Some people can post some sweet looking suicides, but what is the max stable frequency they can run at.
Rabbi_NZ is at 268MHz using two 512MB modules - Super PI 32M stable! I'd like to see BH-5 do that. ;)
yep, looks like 2x256MB to me.... i have a screenie like that too.... also SuperPi1M @ 272x10 6-2-2-2.0 Dual ;)Quote:

EDIT2: nevermind... i've seen better screenshots on macci's website but not with 2x512MB ;)
