Post your overclocks !

Ok, Prime seems a bit more stable now, here is a screenshot...

Well Nikhil, the CPU is fine as Prime has been running for a few hours now. So what could be the problem ?

 
Now, try running the "BLEND" test of Prime 95. If it fails, then I think your RAM is the culprit. Maybe you got fake Hynix D43!!!

And PRIME has not been running for a few hours!!! It has max run for around 1 hour. You need to keep it(small FFTs) running for at least 12 hrs before you can say your CPU is stable..... Run Prime 95 for 24 hrs(to be on the safe side). Then report back if it has passed the ful 24 hrs with a screenie.......

Then after running ir for 24 hrs, run Prime 95 blend test. If it fails, then RAM is at fault.

Oh hell, problems ! Please help !

Prime fails after about 10 minutes. Tried thrice. Here are current settings :

CPU : 2250 Mhz (250 x 9)
RAM : 2.5-3-3-7 (204.6 Mhz 5:3 divider)

Increased DDR voltage to 2.7v and CPU to 1.450v but no difference. Is it a CPU problem or RAM issue ???

change the timings to 3-3-3-10 ......and try ...

download memtest86 ....burn it on a CD and test ur ram it will tell u wat is the problem ...... prime95 is basically for CPU not for ram ...
 
Ok, will test Prime Small FFT's test and report, but I dont' get it. People here have safely clocked Winnies to 280Mhz and how come mine fails at 250 ?
 
VOLTAGE!!!!

They would have increased the voltage....

But I do not advise that for you right now. A new proccy should be allowed some time before increasing the voltages.....
 
Oops, look what I found

The manufacturer specified timings are 3-3-3-8, not ultra low latency uh !

Will set it to those timings run Prime and post back...

C'mon Nikhil, didn't I mention that I am feeding this baby with 1.450v as compared to the stock 1.400v ?
 
That doesnt look like original hynix. Its made by some crap company. SPD timings mean nothing. My ram is rated at 3-3-3-8 at DDR400 and does 2.5-2-2-10 @ DDR500.
 
Has any of the folks here with the DFI mobos tried the 5.10-X Oskar Wu beta bioses for oc-ing a Venice ? Have been flashing and testing bioses for the past hour or so. Looks like 5.10-3 is good for stable oc-ing of TCCX sticks but apparently there is no conclusive evidence as to which one is good for performance - prolly 5.10-2 even for TCCX ! Will post some oc-ing shots later after testing those bioses myself.
 
Well using 5.10 , but no venice,
nd yup the -2 bios is giving better results than -3 for many ppl out thr with TCCx
u mite wanna try tht if ur flashin now :)
 
^^Oh great, so you're using the 5.10 bios too Rocky ! Thanks ! I take it that it has been stable. The 5.10-2 bios gives nice performance boost, but I'm having some problems in posting high clocks. Should prolly experiment with it more. Have settled with 5.10-3 for now. I hope they conclusively clear up the rationale behind the Tref issue. A64Tweaker or even simply auto as in my case seems to be a better choice for now.
 
Just wondering, why havent they gone beyond 3/10 as the Official Bios?
Most people tend to be going to the Beta Bios! BTW, what BIOS would be recommended for the Venice and RAM thats neither TCCx nor UTT ;)

SPD time doesn't mean anything ..... mine is also 3-3-3-10 @ 200Mhz

Even Rahul said to increase the latency to 3-3-3-10

get memtest86 its better than prime95.... if u r testing ram ... ..thus u can pinpoint the problem ..

make ur timings to 3-4-4-10 and see how much u can push that ......
 
First 3G overclock of a Venice 3000+ ;) !

HeHe, had to flash bioses several times since I was trying to get a handle on the 510 bioses as well as the PDP RAM. Ultimately, 510-2 bios appears to be good for tightened latencies and 510-3 for higher clocks. This is without fiddling with Tref too much. And setting all the parameters from the BIOS rather than in windows. An optimal Tref may flip the balance.

The VCore of 1.63V is kinda an overkill for the relaxed latencies that I've used. And there is still lotta headroom for the chip and quite some for the PDP too. PDP was fed 2.79V (0.04 over-volt by mobo) and was hardly hot.

The oc was done with the room temperature varied between 22-25C. Finally settled for 25C. Prime tested for a short while, but saw no apparent instability. Will go for full scale Priming next week when I could possibly squeeze in more time to goof w/ h/w.

And TBH, I think I had more fun ocing my KVR on the ABIT AV8 + Winnie 3200+ rig :P !

The rig is:

A64 Venice 3000+
DFI nF4 Ultra
2 x 512 PDP XBLK RAM
XP-90 w/ TT Smart Fan
LeadTek PX6600GT TDH
Antec Neopower (and partly with TruePower 480W)
Bunch of fans to cool memory and mobo

 
AWESOME!!!

Again, what is the stepping of your Venice???

Whatever, you are damn lucky......(to have got a good oc'ing chip).

THE NEW KING OF OC'ING at TE!!!
 
Thanks Switch. And hopefully there will be many more ;) .

And All Thanks to Darky and Eddy. If it were not for Darky's post enthusing all of us here to go in for the Venice, I may not have chosen to go with the Venice.

Thanks a bunch Darky :) !

The stepping is DEVIL 0666FACE :P !
Aha ! I'll let you and Quad guess !
 
yeah... darky has been even my inspiration for oc'ing..... I was not as serious abt oc'ing earlier though I wanted to do it...... thanks to him, I got better and better.

You can see in the third page of this thread my very first post at TE. At that time, I thought Darky was great for touching 2.7GHZ(even now I do, only thing is, I have also come damn close). Today, my system is stable at 2.5 GHz but at high voltages.

Unfortunately, my chip is one of the worst made by AMD. The 0501 chip. They are really terrible oc'ers. Most people find that it tops out at 2.5GHz.
Anyway, now waiting to see Darky's final OC on the Venice. Last heard, he was frustrated with it as it would not go beyonf 2.65. His Winnie went higher than his Venice!!!

HEY!!! I am not keen on buying a Venice(no cash!!!:sob: ). I was just curious that is all....
