Think he means PAT
It's what Abit call PAT (Performance Acceleration Technology). Look in Advanced Chipset Features in BIOS and set the Game Accelerator to Auto if it isn't already.Ok. What's PAT?
Ah, I know what you mean. The thing with the F1, Street Racer and something else setting? It is set to auto already.
I am starting to suspect my memory. Will run memtest tonight.
Hi planetgong,
Did the person who sold you the CPU tell you it would do 3.5 on AIR - ie he wasn't using water and just didn't tell you?!
To work out if its actually the CPU or the memory then change the fsb:mem ratio to 5:4 or 3:2 so that the memory speed is v.low then try to increase your overclock. If you can get the CPU speed up this way then it looks like the memory doesn't meet spec and you should get it replaced!
If you can get the CPU faster when not at 1:1 then like you say you can run memtest starting at a lower fsb and increasing to see at which point you start getting errors.
BTW, you do have the memory in the right slots? In the right channels not side-by-side (just thought I'd check!)
That reminds me, what Vdimm are you running? I recall reading about the IC7 Max3 having problems when it's set to specific values (2.9/3.0? can't remember). Anyway if you're running at stock Vdimm then you'll probably need to increase it. Try 2.7 & 2.8.
I do have the memory running side by side - is this wrong. There are two lots of two slots(if that makes sense) so I presumed that this was the correct way of doing it(in slots 1&2). What is the correct way of doing it?
Aha! Well, changing that should help - you're running the memory in single channel mode - no idea how overclocking affects that, never tried it like that and besides you don't want to run it like that as its way slower.
Presumably you have the manual with the mobo? If not look here. Page 25 of the PDF:

For dual channel mode you want a stick in each bank, ie in slot 1 & 3, where slot 1 is the one nearest the CPU.
Well that's just silly! Would it not make sense to put the two double banks together.
If anything having it in single channel should help his overclock. It could be that he's hit the max the chip can do. To give a perfect example I bought 2 2500+ for my computer. One was week 31, one was week 34. Now the week 34 was supposed to be a great overclocker, but no matter what I did I couldn't get it up to even 3200+ stable. The week 31 did it no problem. So as has been said before, overclocking is a bit of a gamble. You do your research, buy the items that will give you the best chance of success and hope everything works out... sometimes they don't.
Shouldn't be much of a gamble in this case though, 'cos he bought his 2.8C off someone who said it ran OK at 3.5. Guess the gamble here is whether he actually saw this and if not could he trust the seller!
I didn't see it, and now I wish I had of done. I have tried everything now, Putting memory at 3:2 etc, and still no luck, can't get it past 3.2. Running Memtest as we speak, but if it still didn't go past 3.2 with the divider set at 3:2 then I doubt it is that. Maybe my motherboard just doesn't like it? Still could be my PSU, I have a QTec 550 lying around, might try it with that.
What brand of ram is it??
My Twinmos Twister PC4000 wouldn't run on spd settings at speeds in excess of 240fsb. I had to manually configure the settings to 3,4,4,7 and 2.8v to get it stable at 250 + 255fsb 1:1 with my 2.4c I had.
But like already mentioned, it could be slightly dodgy rails on your psu holding you back or you have hit the chips maximum.
It is AData RAM. I would lower the settings, but if it doesn't work at 3:2 is there any point? And would it be worth it, as what I am gaining in CPU speed I may lose in RAM speed?
Sorry, missed the 3:2 part
Have you got the latest bios??
I did hear that it resolved some issues with o/clocking as such??
The mobo I had off Ryan had the evaluation bios on it and was rock solid.
Plus don't go over 2.9vdimm as you get into the vdimm instability area. This can cause various problems including crashes. The chipset can't control the voltage correctly over 2.9v unless a mod is done.
Apart from that mate, it looks like you may have hit the ceiling of the chip.
I haven't flashed the bios, as it is something I have never done before, and I don't want anything to go wrong!! Where can I get the latest BIOS from , and anyone got any handy pointers on how to do it?
Sometimes mobo manufacturers supply a Windows program to update the BIOS, don't know about Abit. Asus Windows BIOS update seems iffy so usually I do with a DOS program booting off a floppy disk. Never had a problem yet.
Best check your manual about how to do it. Go to the Abit website for the BIOS itself, will probably have instructions there too. Always a good idea to have the latest BIOS installed!
Think I will give it a go. Bit annoyed really saying the guy I bought it from guaranteed it was a good clocker.
How you getting on with this??
