Mobo=Asus A7N8X-X
w/2600 Mobile processor w/I stepping
12.5X166 is the best I can do.
I up the voltage to 1.65
and the FSB to 200 and X12.
Nota! No posty.
I know you're laughing. Me too. The 2700 ram is the problem? But that is all the FSB options seem to give me. 100/133/166/200?
I'm lost.
Any help would be appreciated. Didn't really want to go with the pin mod thingy. Never really understood it either. Hmmm???

Cmon Yo, I thought you were better than that! I have the same board. Did you read thru the manual? You have to change the System Performance setting to USER DEFINED to release the FSB settings.

Your PC2700 RAM is probably gonna hold you back from hitting 200mhz or beyond, unless you keep the Memory Frequency setting on BY SPD...I doubt you'll be able to run in SYNC.

Keep the memory timing on OPTIMAL, lock the AGP at 66mhz, & keep both Spread Spectrum settings (FSB & AGP) disabled.

BTW, lower your multiplier to 10x until you get the FSB settings figured out...& you may find you'll have to increase the vcore higher than 1.65v

Thanks Jam!

I'll let you know how it turns all out.

Thanks again!

Jam,

I worked it up to 200X11.5 @1.65V while using your advice about the memory and AGP settings. Seems to be ok while running folding.

Also tried 200X12 @1.7 volts but it shut down windows and folding after a minute or two.

Do you have any other ideas? Or do I have to dump some more dough for some 3200 ram?

The temps seem to be running stable at 50C & 26C while working folding.

TIA!

YO

Is there a +0.1v increasement towards to ur RAM? Try using 3-3-4-8 setting with 0.1v increasement. See if that helps.

TMP-Man

GOT TMP?

TMP,

Yes it does. So I need to raise it a tenth?

And my memory timings show:

Active precharge delay 7
Ras to Cas delay 3
Ras precharge delay 3
Latency 2.5

Where do I put the 3-3-4-8 numbers at?

TIA!

YO

I guess I should have asked does it do it automatically if I raise it a tenth?

YO

If you have the memory timing setting at BY SPD, it's running at 166mhz. If the FSB is at 200mhz & the memory setting is 83%, you're still running at 166mhz. If you change it to SYNC, then it will run (or try to run) at whatever the FSB setting is. Right now, you're not overclocking the RAM, so changing the RAM voltage or other settings aren't necessary. For best performance, the RAM should be running in sync with the FSB....I don't know if you'll be able to pull it off with PC2700 though.

Your PC2700 ram is going to be a major bottleneck @ anything over 400FSB, unless you decide to run async. However running async takes away from the performance gains you get while overclocking.

Would getting some PC3200 ram help? Yes it will, Do I think it is worth the few megahertz you hope to gain in addition to your current overclock? No!.....but I'll let you be the judge of that. BTW if you've got a good HSF, you ought be able to squeeze a couple more out of your FSB if you raise the Vcore a notch or two.

Enjoy...

Jam,

If I had of raised the voltage to 1.75 (max)when I tried to run at 200X12, do you think windows would have stayed up and running while folding? Just curious.

Thanks for all of ya'lls help!

YO

"If I had of raised the voltage to 1.75 (max)when I tried to run at 200X12, do you think windows would have stayed up and running while folding?"

I really can't answer that...it's possible. You won't know unless you try.

I've been playing around with this 2500+ Sempron/Tbred that I got & wanted to hit 200mhz/400FSB, but was reluctant to raise the vcore. I really didn't wanna go higher than 1.75v either, but I wanted 200mhz. I was able to hit 195mhz at 1.775v, then I finally went for broke - 1.80v. It's now running quite stably at 2100mhz (10.5 x 200mhz) with idle temps in the 30s.

I don't know that I'm gonna keep it in my Asus board, I just wanted to see what it would do. The Soyo board that I intend to run it in doesn't have all the overclocking features of the Asus. I see the 2400+ XP-M is still going for about $80 at newegg so I may eventually go for that.

Jam,

Thanks again! BTW, I hate to keep bothering you, but why do you have 1.8V and mine only shows 1.75V max. Is that based on the chip installed or the mobo capabilities?

I sure am glad I got the same board as you.
lol!

TIA!

YO

also jam,
the AGPs can handle more than the 66MHz default right?
increase in AGP clock will give better video performance. So why lock AGP?
Isn't it sufficient to lock PCI to keep the hd happy?

Good Luck and Happy Computing,

YO,

I'm at work right now so I can't actually check my PC, but I know it doesn't stop at 1.75v...I think it goes as high as 1.85v in 0.025v increments. I thought that YOU didn't wanna go higher than 1.75v. I don't think this would make a difference, but what BIOS version? I've updated to 1010.

Kailas,

PCI & AGP go hand-in-hand...AGP is PCI x 2. Whatever you do to one will happen to the other. There may be a slight gain in performance if the AGP is increased, but I don't think it's all that significant. It's generally not recommended to raise the PCI higher than 38mhz because of possible data corruption (IDE uses the PCI bus). My personal limit when using boards that don't allow locking the PCI speed is 37.5mhz...that puts the AGP at 75mhz. I've never had any problems when doing this, but I only did it because I had to. I suppose the AGP setting is something else that could be played with, but I'd keep it locked at 66mhz while overclocking the CPU/RAM so that it's one less thing to worry about. Once the CPU/RAM settings are finalized, you could always go back & play with your AGP...lol

I'll check my bios tonight. Thanks!

YO

Jam,

If you're still around, I checked my bios and it is up to date. And I'm currently running at 200X12=2.41ghz. The Vcore voltage adjustment to 1.75V did the trick. But I also changed the AGP to 73mhz, and it helped also. Set my cpu fan to max. Currently running at 55C/28C after running folding for about 1 hour now.

You know, I use to think that whatever I did to a cpu, I wanted to stay down in the 40C degree range when working a cpu. And now I think that sometimes you just have to give in to a new way of thinking. lol!

Thanks a bunch for yours and the others help.

THIS IS AN AWESOME BOARD HERE!

Now I just need to find some dirt cheap 3200 ram. lol!

Take care!

YO

Glad to hear you got it running the way you want. I agree that this is a great board...you should have listened to me months ago! LOL! ;)

What are you using to monitor your temps? Asus Probe? BIOS? or something else like MBM5?

With my board, Asus Probe seems to report the CPU temp much lower than the BIOS. Currently Probe reports my CPU temp at 32C/board temp at 19C. MBM5 reports the temps as: Case 19C/CPU Diode 46C/CPU Socket 32C. BIOS reports the CPU temp as 46C.

This really isn't a concern but I do wonder why Probe reads a socket temp, when MBM5 & the BIOS apparently read the diode? If you use Probe, I'm curious to know if you're experiencing the same temp differences.

Anyway, good luck with your new setup.

Jam,

IMO the socket temp and the diode are one in the same. The diode is the only thing that I know of that reads the temps. Hopefully you didn't get the wrong diode with your board. But who knows? Maybe I have the wrong diode with my board. You have owned your board longer than I. So I would think that there is a version change in order. My probe says version ???? Sorry, I just realized that I'm on my 1400 computer. This folding has taken a toll on me. lol! I'll get back to you in a minute or two.

YO

Jam,

My version is Probe V2.20.03. Good luck!
