OC Checkup

[Ansur]

Since I'm still a bit new to the concept of OC-ing, I'd like to ask some specific questions considering this, based on my specific system.

At the moment I'm running at 13.5 * 170, which is stable.
It seems I can't get any higher than that.

CPU voltage: 1.75 (normal: 1.65).
RAM voltage: 2.8 (normal: 2.6).

The 'problem' is that I'm thinking it would be better to get a higher FSB, so my RAM (which is PC3200) gets more useful.
I've tried running at 11*200, but that doen't go well.

Are there tips or so to get some improvements? My knowledge about voltages aren't quite optimal, resulting in the fact that I'm not sure to what I can go, and I'm really not interested in damaging any of the components.

About RAM timings: they're still at default level, I've tried some things with them, but mostly I have to reset my CMOS to get to start up my PC again. I think 11 - 4 - 2 - 2.5 was do-able at 11*166, though I'll have to check that again.

The stepping is a AQZEA, my temperature stressed with the little OC is about 48 ~ 49°C

Well,i can run 200*12 fully stable at 1.6 vcore with a coolermaster aero7+

your temperature will be much lower,mine is at 40oC this way

Welcome to XtremeSystems!

Ansur, first off you need to find out what yoir maximum FSB is. So lower the multiplier and raise the FSB. If it is good quality PC3200 more than 200FSB should be easy to get and as it is PC3200 you should be able to run at 200FSB with no problems. They once you have found out your maximum FSB raise the multiplier until the chip is maxxed out for your cooling.

The NF7-S is a very good board and you should have no problems hitting high FSBs with it. What RAM are you using? It says Twinmos but ideally we need to know exactly what chips this memory uses please. :)

Thanks,
Craig

Ok, I'll get right on searching my max FSB.

About those exact twinmos chips... can those be found on the RAM itself or via software ?

[GJ]

probably via a software too,but i am not sure of any

[ctgilles]

On the RAM ;)

[CCW]

Look at the memory chips themselves, they should be a retangle shape, known as TPOS memory modules. If you can tell us what make they are it would be appreciated. There wont be any software that can do this.

[Ansur]

Alright, I've think I got them.
M-tec 0335D
Is this what you guys are looking for ?

Btw, I've set my MP to 10 and I've been testing with SiSoft Sandra Burning Wizard to a FSB of 200.

I just read Richbastard's thread on MemTest (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=20864), so I''ll be testing higher values with that.
I think I'll be able to to post the maximum FSB here soon.

[CCW]

Yes that is what I am looking for. TBH, when you get near 200FSB I wouldnt be surprised if that RAM held you back, the M-Tec chips wont OC much at all. :eek:

Craig

[Ansur]

First of all, thanks for the welcome. I overlooked it the first time

About the RAM chip..., not really great to hear :)

It's a bit weird... when I let that Sandra Burning Wizard run for about 5 iterations, I get no problems.
When I do the memtest, already after the first iteration I get 8 errors...

I'll check my brother's computer for what RAM chip he has, he doens't OC, so it might be no problem for me to get my hands on that one, though probably it'll be the same :(

Anyway, I guess I could say that my maximum lies at about 200Mhz.

[CCW]

Possibly, given extra voltage and cooling those M.Tec chips may go further but generally they dont. :( The RAM will be your limit as Im sure your board wil lgo much higher.

Still at 10*200, I upped the voltage of my CPU to 1.8v and my RAM to 2.9v

At an other forum, I was told that 2.9v should be no problem from Twinmos.
And what about the CPU, is 1.8 a bit over the top, or should this not be harmful?

Now, memtest only indicates errors after the 5th iteration, so I'm progressing :)
Maybe lowering to about 195 should be OK, I'll test this later on.
Unfortunately, I haven't got the money right now to get better RAM, maybe in the future I could get corsair or so, but that's not for now.

So how do I go on from here?
Is it best to try improve the MP, still using the same FSB?

[Ansur]

Now running at 11*200, and even after 10 iterations still stable, though I think I might be pushing it a little.

I'll try raising the MP with 0.5, but if that shouldn't work, should I return to 13.5*170, since this is theoretically better?

[Soulburner]

Well 13.5x170 only has a 95mhz advantage over 11x200, so given the high difference of bus speed I would say its still not faster.

[Ansur]

13.5*170 still seems to be more stable though.

Although Sandra Burn-in doesn't give any errors, I still get sudden reboots while eg. playing BattleField.

Guess I'll have to get some Corsair RAM ;)

[GJ]

strange,with 200*11,1.6vcore it is stable as rock at me

[Ansur]

Probably as CCW says, it's the RAM :(
And I'm still not sure wheter it's OK to give my CPU so much volyage... let's hope I don't have to lower that too :)

[Soulburner]

Looking for Corsair? I have some 2x256mb Corsair XMS 3200 for sale...PM me if interested.
