In Prime95,
FATAL ERROR: Rounding was 0.5, expected less than 0.4.

What does the message above means?

Awwww.. Clock for two days.. Still unable to find a stable rate.. Damn.. A question here.. I run SP2004 for CPU + RAM stress test.. Ermm.. Is it must let it run without any disturbance? Because if I load something, the test will returns error..

EDIT: Btw, does KVR DDR2 safe with 2.4v? I don't wanna fried my RAM.. Well erm.. It's D2N5, not found in RAM Hand Book..

Found the sweet spot at last..
Dare not go any higher with stock HSF.. Idle 34c, max load 55c.. Btw, 246 x 11 (2.7Ghz), 1.575 vcore, 2.0 vdimm.. Is it ok for A64 Athlon to have 55c? A bit worry thought..

EDIT:

3500+ Orleans F2 | Shengz | BIOSTAR TForce 570U | KVR DDR2-667 | AMD Stock Cooler | 2706MHz

About the temperature.. Mobo hardware monitor software shows me 54/55c while speedfan shows me 45/46c.. Which one should I trust?

Thanks for the info. I will try it later..
Errr.. Ignore the CPU-Z vcore.. I have no idea why after I oc'ing for two days, and the vcore gone mad.. Maybe.. processor fried soon...

Need some helps here.. When I doing prime test, if I run some programs and the prime test will returns error.. But if I let the prime test running alone without open any other programs, there will be no crashed or error occured.. So is it considered my oc stable?

Oh goshhhhhh... My CPU really get me gone mad.. Prime stable for 48 hours.. But once I simply run programs, it will crash.. What the heck is holding me back? My RAM? Or the mobo? No BIOS update available currently.. Quite regret getting this mobo..

Priming now, hopefully it goes fine..
The max HTT I can use is up to 250, anything over that, it won't boot or not stable. I'm on stock HSF, so wouldn't risk my processor with > 1.6v. And RAM I have use up to 2.1v. It's the max. I think same to you too. 1.95v is the stock vdimm. I wonder why? It suppose to be 1.8v, not?
Btw, does single or dual channel RAM affects in oc?

EDIT: What about AMD processor driver? I've updated my to the latest version. Does it affect overclocking ability?

Yea, I'd disabled CnQ since I oc, smart fan was disabled at default.

Sorry the attachment a bit messy because of low screen resolution on 15 inch LCD.

This are the settings in BIOS currently:
HTT: 246
Multiplier: 11
Vcore: 1.575
Divider: 667
Vdimm: 2.0
Timing: 4-4-4-12 (1T)

Timing has been tighten up. Atm, Memtest, SuperPI 32 passed. Will start prime95 now. If the system rock stable, I believe this is the most stable settings currently. Can't go any higher already.

Yo allenultra, thanks for sharing this settings!
Only able to oc tomorrow morning, have guest sleeping in my room. Save down the whole settings in my notepad before you edit it. Just joking!
1.25v can get me 2.5ghz, but 2.7ghz needed at least 1.55v to boot, and yet not stable. Btw, I read up somewhere they said the temperature for A64 should not over 60c. At 1.575v, my max load is up to 48c(Speedfan/CoreTemp)/57c(mobo monitor software ) currently, I guess, it's ok? Hehe..

Any chance you found some guides on ram timing for newbie?
Advance guide might confuse me. I will try google around.

EDIT: Btw, when my HTT over 266, there is no chance for 10x multiplier to boot.

Yea, after the ram timing shared by PCcrazy/allenutra. Before that, there is no way for 9x 266HTT, not even 8x.

How much vcore at 250 HTT? Prime stable? And how about the temperature?

This post has been edited by Shengz: Jan 21 2007, 06:18 PM

My processor is idle at around 27c during night time, hot evening 34c, midnight 23c. 1.45vcore. When it was virgin(I mean stock ), I seriously don't believe the temperature.

I tried to touch heatsink. And I trust the temp reading from SpeedFan/CoreTemp.

Edit: No, no air-cond in my room. Whenever I notice my processor idlig more than 32c at evening, I will just leave it there. The room is just soooooooo warm!

Your CPU and chipset looks warm. You may need to change after market HSF if wish to go further. Btw, make sure your HT Link lower than 1000 for stability and overclockability.

Basically both are the same. Main point is, TForce series is built for OC purpose. It has solid caps around the socket and more features for overclockers in bios.

EDIT: if you have further inqueries, you may ask in hardware questions and answers section.

You didn't try multiplier of 11? Its not worth for so much vcore but just 200mhz more. Do check your temperature too.
