P3 750 on Asus P3B-F.....

[Jethro]

Ok, no laughing at my old warhorse of a mobo. :D lol...Anyways, the question I have has probably been beaten to death but I'm gonna ask again....I'm runnin a slot 1 P3 750 chip at 900 (Familly ID 6, Model ID 8, Stepping ID 3) 120 fsb, stock heat sink/ fan, stock voltage on an Asus P3B-F mobo. 320mb Hyundia (sp?) PC100, VisionTek Ge-Force 2 GTS 32mb and Det. 11.01 drivers. After reading a bit here on the forums, I gotta ask how high I could take it. I've tried runnin it at 124 fsb, 930mgz, just not stable. Is it my cheap PC100 that is holding it back? Should I bump up the core voltage a bit? I have the side of my case open with a huge house fan directed inside it....Sounds like a jet engine. lol The temp reported right now by Asus probe is 26-30c. It will post and load windows at 930mgz, but games crash and are unstable. Other specs:
WinMe
Sound Blaster Live!
LynkSys 10/100 NIC
Creative DVD decoder
Creative 12X DVD drive
Imation 12x10x32 CDR drive
13 GB Maxtor 5400 rpm IDE hdd
20 GB Maxtor 7200rpm hdd.

Any ideas?

I don't know the mb, so you'll need someone with experience there, but if it is running in windows @ 930 and stock voltage, I would guess that there is more to come, but you may need to set jumpers with that board. My 750 required a very small voltage boost to 1.70 to go 968 steady, but the 1 gig was unhappy like yours until I upgraded my old pc133 to Crucial cas2 pc133 memory and bumped vcore to 1.75v. Now it is solid.

However, I did not play with IO voltage (which is default 3.3v), so I may have been able to avoid the memory upgrade that way. I may try it when I experiment with gig plus speeds.

Given what little you have worked with so far, I'll bet it will give you a bit more.

Good luck.

No jumpers....I have it set to Jumper Free mode. To much of a pain in the ass to switch them damn jumpers around. haha. :) Hmm, Maybe I'll go play around with it a bit right now and see what I can get.

first of all your board may be old but its a damn good bx.anyways it very well could be your ram not likeing the higher bus speed if u can set your ram cas to 3 3 3 6 and that usually will let u go higher and if your only at 1.65v you can go up to 1.85-1.9 but dont let your temps go above 50 max if i where u i would try and borrow a stick of pc133 and see how much potential that chip has good luck

Will 133 RAM really make a difference if my board won't support it? I'm pretty sure the P3B-F will only support PC100. If it will make a difference I'll get me some and see what happens. If not I dont want to spend the money if I wont gain anything from it. BTW, what is a 256MB stick of high quality PC133 goin for these days?

And after a bit of messin around with different FSB settings and voltage settings, I couldnt get it to run stable higher than 120. No matter what the voltage. It would post and boot to windows fine. But as soon as I started 3D Mark 2001 or UT, after a minute or so, it would freeze. This was at 124mgz. Wouldn't even boot at all at 133. Unfortunatley I don't have a choice there....Nothing to select between 124 and 133. So is this definatley a RAM thing or????? Should I look at a mobo upgrade? How do ya'all feel about the Asus P3V4X? Or do ya think I can get more out of this chip with the P3B-F?

are you sure that your board doesn't support PC100 ram? I have an ASUS P2-99B bx/zx board and I'm using a stick of PC133 128 MB RAM, together with two PC100 64 for a total of 256 MB RAM, but my fsb is only at 100Mhz right now because of my Celeron 600@900.
I'm sure that your board can handle PC133 ram.

Well I know that it will physically work....But it won't run at 133mgz will it? I was under the impression that it would automatically clock down to 100mgz. Correct me if I'm wrong......

Is it possible that the P3B-F has a bios upgrade available? That is going to be a big jump from 124 to 133 fsb.

I thought memory ran at the fsb speed, ... I've seen some say one of the reasons they like to go past 133 fsb is that it gooses memory speed up.

I do know that going from an old pc133 stick to a new stick of Cruicial Cas2 did the trick in my machine because I did nothing but turn it off and pop in the new memory. I did bump the vcore to 1.75 from 1.70 since I had been running at 968 with that. Previously I had gone as high as 1.85 v with no luck. It has run 1 gig from the new memory installation onward without any hitches in Prime95 through the torture test and 14 hours of the 16 hour self test (my son keeps coming in late and turning off the computer!), along with any game or movie we can throw at it.
