Just got my 1.8A...New Question, PLZ Read!

[ctk1981]

SL68Q MALAYSIA
L224856-1513

My ASUS board will be here tomorrow, ram should show up then too. I'll be ready to OC for sure by friday!

So what do I potentially have here? Good OC potential or a potential dud? Just based off of code of course, I know any given chip could be a potential dud for OC.

This is going to be quite a change from my usual AMD stuff!

EDIT: Well after getting done with stress testing and memtest, im at 145MHZ. Very very odd....why you say? When I had my AMD setup I could never stabily overclock passed 145MHZ. I always assumed a item on the PCI bus was holding me back. Could it be the power supply? Its a Sparkle 400 Watt PSU. I got a pretty full load of components. 2 hard drives, DVD, CD-RW, TV Tuner, FIC Radeon 9700, Ultra 66 controller card, Philips Acoustic Edge 706, etc.

5V line looks good, 3.3V line is also good, 12V seems low....11.71 or something like that. Whatcha think guys?

What is the packing date??? newer 68Q chips around here in the last week or so are getting 2.6ghz at default so 2.8ghz with 1.7v is very doable....

Good luck....

Pack date 8/15/02

You will probably get past 2.0ghz, mostlikely higher. That is if your RAM can handle it and you can lock your PCI/AGP bus. I also recently made the switch to Intel from AMD with all the paper launches. I still can't find a stupid AXP 2400+ or 2600+ let alone one with a faster memory bus. I got a great deal on a 2.53 and have it clocked at 2.66Ghz with my memory around 180Mhz. I have an Abit SR7-8X with 512MB of Corsair PC2700. I had to go with the best performance for the money and oddly enough this time around it was Intel. I won't be upgrading anything but video card and monitor before next year around this time. I will definitly get a new monitor and new vid card at christmas. I'm waiting for the new cards to come out. But anyway, yes I think your chip should do well.

 

[Duvie]

Just about gauranteed 2.4ghz at default vcore, but I think you will be like crazysaints and thugsrook's recent 1.8a 68q chips.....

All im seriously hoping for is 150MHZ FSB with a voltage lower than 1.7. If I can get that, I will be very happy. The asus board im getting is with the newer 845 chipset, it should have AGP/PCI lockout. Hoping to hit 150mhz, switch the memory to 3:4 and run 400mhz DDR. If I can hit higher, fine! If I can only hit 150 at 1.7V, thats fine too.

I just hope I can at least hit 150MHZ!

Asus Board P4PE/L
Corsair XMS 3200c2 stick 512MB

EDIT: Ya know, the only reason why Im upgrading to a P4 this way was to pump data faster to my FIC Radeon 9700? My 1900+ just wasnt cutting it for me! Overall I think this should be a very good upgrade for me. Theres always a need for more speed!

That board definitely has PCI/AGP lock. In fact, you can adjust the PCI/AGP busses independantly of the FSB if you want to OC 'em a bit. I've been testing a brand new SL68Q 1.8A on a P4B533-V and I get 150FSB at 1.6v so your chip should be similar. My chip has a 9/04 pack date. I could almost certainly hit a bit over 2.8GHz for a nice 1GHz OC if I upped my vcore to 1.7v, but I'd rather not go that high. Besides, my Corsair XMS PC2700C2 is reaching its limits at DDR400.

Yep, 68Q seems to hit the 2.6-2.8 range pretty easily. Mine is still purring along at 2.7 GHz default voltage

Ctkelly, you have a week 24 chip (L224), mine is week 25, I am guessing Crazysaint's chip is in that time window too, his pack date is 9/4 (mine is 9/5). Chances are good that you've got yourself a contender

Well I got it all together tonight. Ive installed XP about four times with various problems. First try, I think I tried installing too much stuff all at one time....seemed to be a conflict with the drivers for the Radeon 9700. Second try ended up having problems with the USB 2.0 installation fix, which resulted in tries 3 and 4. I follow the directions, but when I choose to install the driver they want I get a code 10 error (device cannot start) and the USB never does work again. On the fourth try I suddenly realized I wanted to go back to Windows 2000 Pro anyways. So here I am finally reformatting again with Windows 2000.

I know the first attempt was a driver error, it could restart make it all the way to the desktop...and as soon as you tried to right click, or click on the little ballon to increase your desktop size/quality it would lock up. Ah well.

Right now I am running 2.7Ghz, 150Mhz FSB at 1.6V (actual is a lil higher of course) and 400mhz DDR. Once everything is installed and nice and pretty, I'll go ahead and stress test it. I think Im gonna run the computer through memtest86 tonight while I sleep also. Get that out of the way first.

Hopefully my Windows 2000 adventure works out better. Download the SP3 for it and go on from there.

You're getting a little ahead of yourself. Leave everything at default until you get your OS installed. Then increase your FSB a bit at a time (starting at 133FSB) with the mem ratio at 1:1 running prime95 for an hour at each step. Once you get to your max CPU OC, back it off a bit and start in on your RAM. Unless you know exactly what your RAM can do, OCing them both at the same time is a waste of time because when it fails a stress test, you won't know what reached its limit, the CPU or the RAM.

Sorry to hear you're having trouble with the install; it can be a bit tricky on these USB2.0 chipsets.

What worked for me when I had trouble was to install WinXP, restart, load the ASUS QE fix, INF driver, then the USB2.0 driver (DO NOT RESTART UNTIL AFTER THE USB2.0 DRIVER!), restart, and proceed to install the rest of the drivers (LAN, ethernet, video, etc.) with a restart in between each one. I know that my suggestion smells of Win98, but it's worked for me every time (I have 2 systems) and for my friend's system when he was having the same trouble.

hope that helps

Erik

PS. ditto on what CrazySaint said

 

[Duvie]

I agree with crazysaint....Everything at default and lowest setting until cpu limit is determined...use prime95 as stress test...stop and test each speed jump with at least 1 hour of testing...if OK move on....When you fail a test then vcore boost is needed...boost at .025v jumps and continue on...Once you hit the highest vcore you personally feel safe with then you stop and stress test it overnight...if it passes you are now set to start memory tweaking...if not back up a notch in mhz and try again.

I also do not like to start connecting all my devices until I am done stressing the cpu and mobo chipset....Then when I install those items one by one and a problem arises it can be more easily isolated...


I think you got the cart 2 blocks in front of the horse in the winxp and current install....

Bah! Sorry boys, Im pressed for time lately. I havent had a day off in over a month. So when I get to going, I wanna try and get it over with as quickly as possible (very bad idea I know) I did find some things out late last night however.

150Mhz FSB seems out of reach for stability. It wants too much juice for my liking.

I can pass 145Mhz FSB on prime for 8 hours without a problem. Memory is at 387Mhz, timing 2-3-3-5. Will run Memtest when I leave for work in an hour or so. Should pass.

My 3dmark2001 SE score is 14416 with no tweaking on the card itself. Previous high with XP 1900+ was 11809. Am I happy? Yes very!

I am running Windows 2000 SP3 without a problem. All the drivers are installed and everything is really smooth/stable at 145mhz FSB. Temps idling 102 degrees according to the ASUS probe, last night it was at about 109 idling.

Memory bandwidth on SiSoft2002 SP1: 2951/2951

As I go I'll update you on more scores I get. Nothing really impressive...oh wait, I guess it is because I bought a 1.8 instead of a 2.66! Ha! Thanks to all to everyone thats helped out!

EDIT: Oh yea, crazysaint: thats the exact reason why I overclocked both. The ram is XMS Corsair 3200C2, it should have no problem doing 400mhz since thats what its rated at. I totally agree with taking baby steps, but like I said..lately Ive been pressed for time and its really bumming me out. I just wanted to get this thing running fast as soon as I could. thanks for the advice though!

 

[ctk1981]

Bump for myself. Any ideas guys? Possible Power Supply? Tomorrow Im yanking the sparkle out and swapping in a Antec 430 Truepower that I had in the dual processor rig. Dual processor rig is running fine off of a generic one thats known to blow up I guess...cant remember the name.

Let ya know what I find out. This should be funny if indeed its been the power supply holding me back on both an AMD system and Intel setup.

Nope not a Powersupply problem. Switched it out tonight, no big deal...rather have the Antec in there.

USB Reference voltage, increased it to high and was able to boot without a problem at 150MHZ FSB. Will stress test this and see what I end up with.
