There ARE "bad"1.6As out there

And it seems I have one of them. When I put the rig together, I thought I'd enable right out of the box the VEN1 jumper on the P4S333 to give the chip more juice. Well, I can hit 2133MHz easily that way. Anything higher and the computer doesn't even POST after I exit the BIOS.

Then I thought I'd put the VEN1 jumper back in the default position, since I was getting fairly high temps. (53C full load).
Nothing. Doesn't turn on, I have to unplug it and turn it back on to reveal the safe mode BIOS screen. I tried upping the voltage to 1.55 in the BIOS, no help there.

Back with the VEN1 jumper on. (1.59-1.63V as reported by the probe)

Too bad... I've always been an unlucky SOB anyway. 🙂

And to top that, I can't overclock my MSI GF4 4400 to Ti4600 levels either. 🙁

Any ideas to improve my situation?

The rig:

320W ATX 2.03 PSU, 15A to the 12V line (never drops below 11.96V even at full load), using 12V connector (not ezplug)
Asus P4S333 (bios 1005)
1.6A Costa Rica Retail, stock cooling with AS3
512MB Samsung PC2700
MSI GF4 Ti4400
SB Audigy
Realtek NIC
 
well, it depends on how you define the word "bad" 😉

i have 2 1.6As that are "bad" - they ONLY go 2320mhz/145fsb :Q

the reason i say they are "bad" is because i also have a 1.8A that can run upto 2556mhz/142fsb.
i only run it at 2400mhz/133fsb for a nice easy cool OC, and it still beats the hell outta my maxed 1.6As.

im sure some ppl would give their left arm for my "bad" 1.6As 😉
 
Are you using the stock thermal pad or Arctic Silver? What's the cooling like in your case (# of fans, their direction, etc)? If you're using Arctic Silver, did you apply a thin layer as instructed?

More info would be helpful.

Hi, I have 2 case fans, one intake, one exaust. And I have one of those "slot fans", screwed below the video card.

I'm using AS3. I think I applied a thin layer, I wraped my finger in plastic and applied the AS on top of the heat spreader. I think it was ok. Or by thin, you mean a quasi-translucent layer? I did exactly like the instructions on the AS website. Temps are 33-35 idle and can go all the way to 53C when running Prime96 and SuperPI simultaneously for a while. It's hot here where I live, about 27C.

Well, anyway I'm happy with the 33% overclock. Wish I could do it with default voltage, but...
 


<< put your jumpers back in the default position, and try oc'ing more with your meme at 4:3... >>



I can't. With the default voltage I can't hit 2133.
 
I have a feeling your power supply is holding you back. The only 320watt PSU I have seen are the extremely cheap ones that come with those cheap black/grayish cases; they do not even use a real 80mm fan in that thing.
 
I feel likely your PS is not holding you back...the 12v line has 15amps for 180 total watts....that should be more then sufficient....

What mem timings are you using??? If you have mem ratios above 333mhz ddr speeds then either up voltage or run memory at 1:1 ratio....

If with minimal devices installed...vid card, 1 (yes 1) stick of ram, HDD, cd-rom...no pci devices yet....temps look fine...memory at underclocked mode....

If you can't do that above then likely it is just a dud in terms of ocing potential....


 
Did you try setting your CPU back to normal speeds (1.6 GHz) in the BIOS, then taking off the jumper for increased voltage, then going back into the BIOS and try setting something like 2.13 Ghz @ 1.65 V or so?
 
na, if he needs the 1.6v jumpered booster to bootup, then he aint gettin much further then that,

my 1.8a needs the booster @ 133fsb to bootup. that takes me upto 137fsb. at 138fsb it wont bootup again. so get an extra 5fsb and 90mhz from the booster - dont exspect much more then that.

even using the 1.7v wire mod, it only takes me upto 141fsb.
 
Thanks for the input guys. Anyway I'm getting a 450W PSU, and selling my old one. Even if it doesn't help the oc, at least I'll be sure I have the juice. I'm also getting crashes in games, they suddenly go back to the desktop. &Iacute; think I will put my memory in the most conservative settings and see if it helps.
