While people are enjoying there dual core cpus playing the latest games and rendering twice as fast big Wayne will be there running his new and improved 96hour hextuple-prime XtremeXtremeStability test :rolleyes:
Wayne your gonna get hiccups along the way no matter how "stable" your cpu is, its just how pc and pc software is. theres to many other factors involved.

I have to agree.

There is just no point other than wasted time IMO.

But hey each to their own :p

Quad prime for that length of time is no more stable than my pc IMO.
You will find your pc could crash or have a hung app at anytime and this does not mean the cpu is not stable.

Its the nature of a windows environment.Even on stock systems SH** happens.

I agree, id rather be playing Oblivion..


btw Have you not broke that 2.8Ghz mark yet ;)

TBH I haven't tweaked for a few weeks.I got a 7900 GT to play with then a 7900 GTX and currently I'm waiting for my 150 gig raptor to come so I can play oblivion.I was running out of space and with me getting new hardware I though a windows re-install was in order.

Selling my 36 raptor raid set so I'm using my lappy until monday :p
 
Did some initial testing with a spare DFI ultra D board and I have broken the 3 gig barrier. This was by no means stable btw - instant failure on prime/sp2004. I wont even be able to attempt to get it stable as temps are just way too high (51c idle - 1.55vcore) so I'm trying for 2.9 with a lot less volts. My a8n32 couldn't get to 3 gig under any circumstances but could do 2.8(12hr p95 stable) with 1.42 vcore (48c load) so hopefully this dfi will get 2.9 stable with reasonable temps. Gotta admit I wasn't overly impressed with the masses of 'options' that dfi is reported to offer, little more than the asus tbh. Proff is in the pudding though so back to some more testing....
 
Had my new rig a couple of weeks now and it looks like i've reached the limit of my cpu. I thought i might post up the results and if anyone can come up with any comments that might get me further, it would be well received.

Why are you running 300x9? Why not 270x10?
Click to expand...

From looking at his memory speed id say 300 x 9 be faster due to the higher fsb and although his memory would obviously be ok at 270 i doubt it will manage any tighter timings than the 2.5,4,4,7 even if it is 30mhz slower. I reckon fastest setting would be 270 x 10 and then mem on a divider to run at 2,2,2,5. From a benchmark at toms hardware it took an extra 80 on the fsb to compensate running the a64 at cas2.5 rather than cas2

Your right it is faster at 300x9 than 270x10. I can run the ram at 270 with 2.5-3-3-7 1t timings, but with a bit more tweaking i think it will do the same at 300. I've tried a divider but the cpu won't hit 2.7 if i use it, 2.65 at the most.
Also using a divider to run at 2-2-2-5 means running at 192fsb which is a slower mem throughput. At 192 Memtest shows 2245 MB/s, at 300 it shows 2512 MB/s. Toms Hardware should be taken with a pinch of salt.

I take it you have tried for more than 2.6 and been unsuccessfull (unstable).

Another problem could be due to over ambitious memory timings as they are the no1 cause for lockups in my experience.

Hi w3bbo, sorry I missed your post before but yes I was playing with some clocks higher than 2.6GHz but due to issues as yet unsolved couldn't really get them stable and by that point I was fairly bored of overclocking so I flipped it back to 2.6GHz for some normal useage (haha yes I do actually use my PC outside of Primesville).

This is a screenshot from my last OC session, 2700MHz but untamed!



A prime fail is a big no no for me personally, but when the prime program itself freezes or crashes its bad news! :D

Just about to give Call of Duty 2 a spin. . last seen heading for the *COD2 Patch v1.01* <<<<------is this for Opterons too?

Wayne, I don't think that your quad prime thing works. Are you sure there are no program conflicts? The fact that prime crashed when SP failed ought to indicate something. I don't understand why you don't just dual prime 24.14 and leave that running for say 48 hours. Using one program which is known to not stress the CPU properly and it being a third party program isn't ideal, especially when there is an optimised version of prime in existence.

It's an extreme test and will run 24/7 on a stock system. Everything is fine for now, been enjoying using an FX-60-Clone, I think that the single freeze I had post testing was due to vCore, now its set one nudge higher (1.425v) I'm sure that will do the trick, I'll give it two weeks of heavy usage and if it run truley solid then its ready to be popped into a new system and sold! :p

Then I will unwrap the next 170 and see how it goes. . .
 
Finally got around to getting my Opty 170 (bought mid Feb) under my Mach II evap head.

Managed to get it straight to 3ghz (300x10) at 1.49v Prime stable for around 16 hours. The Missus logged me off after around 16 hours before I could stop my 2 Prime tests to take a screenshot. This is running on a DFI LAN PARTY SLI-DR mobo with 2x1gig sticks of Crucial Ballistix PC4000 3-4-4-8 on a 9/10 divider ([email protected] actively cooled).

I think it's a week 46, I've got the codes written down at home, only not at home at the moment.

Pretty impressed so far. I'll get a snapshot up next week sometime after I get back from viewing the total eclipse in Turkey ;) Will try & push it further as well probly. :p

I'll be finding out next week ;)

Shame it dosn't include any anti-cheat aswell....but back on topic.

Something strange here.

On my A8n32 I could Prime @ 280x10(2.8) for 12 hours +, 2.9 on the A8n32 would fail instantly on core 0.

On this DFI-UT D I get the same problem but this time its core 1 :confused:

I have only changed the board(for testing), not the CPU.

If I increase vcore then core 0 will fail and core 1 will pass so it seems that core 0 is temperature sensitive and core 1 likes the volts, whats puzzling me is why it is the opposite way around on the A8n32?

You need to set to priority 9 or 10...otherwise you will not get proper load...1 is simply to low, especially if you are going for Uberstability.
