Not All Chips are Created Equal (Sucks to be me)

[CAM]

Just bought an AXIA 1.2 - 266 "y" code (factory unlocked) and put it in. The most it will do is about 1350 stable (135*10/1.85V/28c idle-48c full load/MB temp 22c). I see all of these scores of 1466 and higher and it makes me think what i'm doing wrong. Oh well I guess it's all a gamble unless you buy the already oc combos. Any suggestions would be great.

Abit KT7A, PAL 6035, Crucial PC133 CAS 2 (256), GForce 2 Pro, IBM 30 gig (7200), 320w ps

Forgot to add this question. The highest I can run my fsb is 139. My buddy has the same mb and he can only go 139. Is that pretty much the norm for the Abit KT7A?

I'm getting 148 FSB out of mine. I was stuck at a 10 multiplier till someone here gave me a tip about the K7 CLK_CTL setting in the bios. I set it to optimal and I've been able to break the 1500 mark. 1554 to be exact. That appears to be my 'wall' but I'm happy with that.

Cam, that's a bummer. I'm buying my first Tbird very soon and was going to spend the extra $20 to get a 1.2 instead of a 1.0 Ghz hoping that (1) I would be virtually guaranteed to get a AXIA code chip or better and (2) increase my chances of getting a factory unlocked chip.

Where did you buy your CPU from?
Have you tried using a normal 133 FSB and use multiplier changes to get over 1350 ?

[CAM]

I bought it from mwave and yes I have. Thx for the reply. And TT120 I guess your getting a higher fsb because you have pc150 memory.

Cam, can you tell us your four letter code so we can compare? You know like everyone is talking about AXIA and AVIA as being the best overclockers right now.

[oc jason]

the board limit for the KT7A is 189 FSB-you should be able to hit a higher FSB than thatmaube you need better ram-or maybe its cooling, try lowering the multiplier and upping the FSB to get better performance at the same speed

[Ridenow]

You should realize that some of us are using water cooling to get the impressive overclocks. The other thing you should know is that when you increase the FSB you increase the speed of everything in the computer. Sometimes some of the other components, like SCSI cards, cause stablity problems when overclocked.

I think the FSB problem is with the chipset. Not all Via chips are created equal, just like with cpu's. I have 2 Abit KT7A-R mobos 1 will run 140fsb with 3.6 i/o the other will do 150 with stock i/o. Also have a Asus A7V133 that will do 146 stock.

It is probably better to get a 1 gig AXIA rather then a 1.2gig, it saves money and they seem to oc about the same. If you must have a high OC the only sure thing is a pretested chip.

Don't get to down on only hitting 1350. I have two 1.2 gig chips. With ambient water 1 will do 1440 and the other only 1.33, it wouldn't even post anything above 1350. At first I thought this was a lame chip but when I froze it (-17C) the thing ran stable at 1584 the other 1.2 that seemed to be the better chip wouldn't even make 1500 stable when chilled! The best chip for room temp cooling is not always the best one at low temps. I guess you never know untill you try.

wait a sec
that is what my chip does i cant get it to hit at 1.333 ghz @1.8 Ghz my last resort is for my MC462 to arrive and help me but if it cant i am stuck witha stuborn chip :-(

[proze]

you mean 1.33ghz @ 1.8v...?

Cam I'm not sure that I can give you anything you haven't allready tried but I really don't think that the ram is your problem. I can run mine at 155 fsb with the fastest timings.

If your running any pci cards take them out and find your highest fsb (stable) and then add cards one buy one till you find whats holding you back.

Good luck.
