X2 4000+ Overclock

[covert24]

well ive spent all night tryigng to get my cpu overclocked and stable. im currently running orthos @ 2574mHz (286x9). i had to up a couple voltages since it was kinda stubborn but i finally got a moderate overclock.

Validation

i get 36s on Super PI 1m. i think this is awesome since stock i would get 45 seconds on 1m Smile

Have no idea what my temps are but to quote someone "If its stable then its not to hot"

I have ran orthos for 8 hours and 40 minutes with no errors. But upon restart had to drop my speed frm 2574 to 2525 since my motherboard apparently didn't like the settings.

Let me know what you guys think.

anyone know how i can get her a lil higher? i had to raise all my voltages up to at least .025 and i think the ddr2 voltages i raised .50. let me know wut i can do.

ill get a list wut everything is at tomorrow since im really tired.

no comments? i see how it is

:shocked:

I saw your post before.. not enough info to say why your pc overclocks so badly..

if that is what you think it does.

Why did you label system info as.. validation?

actually for X2 4000, which now cost about $66 on newegg with free shipping.. for 65nm brisbane am2.. should be getting over clock up to 2.8-3.0.

What cooler are you using for your cpu?

What temps are your running?

and...

What mulipliers have you tried besides 9? Don't have this cpu, what is max multiplier?

Are you using a divider for the ram? Seems slow at 367.

I don't use CPU-Z much, but it would have been easier to read and respond if you provided more information in the text, rather than putting some info under place I did not look the first time under validation.

Uh first off, raising your vdimm (DDR2 voltage) by .5v is quite a bit of a voltage increase. Assuming a typical vdimm of 1.8v, that puts you at 2.3v vdimm. Please be aware that raising vdimm significantly without raising vcore much (or at all) can damage or burn out the memory controller on an AMD chip with an integrated memory controller (like your X2).

You should really only be running your memory at 1:1 right now with loose timings. Give it around 2.0v vdimm or less depending on what it needs to be stable.

As far as your CPU goes, as thestain mentioned, you haven't given us much information to go on. However, raising vcore .025v puts you at 1.325 vcore which is not a huge jump in vcore. You should probably try 1.35v and see how far you can get on that.

Depending on your motherboard, you may never get an accurate temperature reading from that chip, so uh, be careful.

First, lower you HT multiplier to 3x, that's why you've topped out at such a low speed. Second, like DrMrLordX said, lower your vdimm to no higher than +.3v, or 2.1v. And last, give your cpu a little vcore, man. To hit 2.8Ghz+, you're gonna have to give it at least 1.375v of vcore, if not 1.40v.

i have a coolermaster hyperx and my temps are around 27*c idle and 47*c load.

and i didint change my ram .5v i thought i said .05v. the multiplier max is 10.5. ive tried everything above 9x. and my ddr2 mhz is set at 533. my Ht link is at 3x right now. and i am going to raise it up to 1.375 and see what happens. My timings right now are at 4-4-3-5 2T so its all good with the tight timings. ill change the divider back to 1:1 and see wut happens. keep the suggestions coming

 

[covert24]

yea and also whenever i try and overlclock sometimes it displays a error message that gives me the option to go to default, restart from your last working settings or continue to boot. when i continue to boot it underlcocks my system to liek 1800mhz. anyone know how to turn this off because i cant find anything in the bios that resembles this. its really starting to piss me off.

That is not always true. My 3600+ Brisbane would boot at 2.8 GHz, but it was FAR from being stable at that speed. In the end, I'm running it at 2.6 GHz with a lot of extra voltage and this is its limit as far as clocks go.

 

[covert24]

yea i think the main problem is my chipset which doesn't have active cooling so its always hot as balls. Going to be putting a small 40-50mm fan on it. i already replaced the slab of dried out thermal paste with some ncie AS5 on the chipset so it is running alittle cooler put still really hot.

 

[DrMrLordX]

Okay, +.05v vdimm isn't such a big deal. If you stick to 1:1 on your RAM, timings should not be an issue. I agree with myocardia that you should try 1.4v vcore. Also, try moving your chipset voltages back to default and use the highest cpu multiplier; that should let you lower your HTT speeds and cool off your chipset a bit.

Remember that when overclocking A64 systems, you need to be mindful of your HTT speed. Generally, you want to keep it below 1050mhz, so you'll need to lower the multiplier as your increase your FSB. Also, when trying to find the max overlock for your CPU, try to keep your RAM at or below its rated speed so you can remove that as a factor of instability.

Actually your overclock looks pretty normal. My Opteron 165 would only hit 2.65ghz, so I decided to pop off my heat spreader, at which point I damaged the chip and now it will only hit 2.6ghz.

Is your chip 65nm or 90nm?

I find the sweet spot for voltage on the A64s is around 1.375v. Then, make sure you lower your memory timings. Try CAS3. Raise the memory voltage. The problem is that you can wind up running at weird memory speeds that are too high for your memory.

Make sure you run a memory divider. I set mine to 266, but you can go lower and it won't make much difference.

Set your hypertransport to 3X.

Good luck.

He has AM2 looking from his rigs page, so CAS3 would most likely result in a no-POST at speeds above 800 MHz.

Try CAS5 if you're going to be running your RAM at anything above 900 MHz or so. I've got 2 GB of G.Skill HZs running at 1 GHz 5-5-5-15 and they run great. VDIMM up to 2.1v is safe for everyday use on most RAM, up to 2.2 or even 2.3V for performance RAM like Ballistix or HZs.

tyea my cpu is 65nm and yea i do have a AM2 platform. ill try to set my Cas to 5 sicne having it at 4-4-3-5 doesnt really make a difference to me so yea.

Use a memory divider. :light:

 

[DrMrLordX]

What timings he uses and what ratio he uses aren't really a concern until he finds out how high the chip will OC. You know . . . isolate and consolidate? I remember reading that somewhere on here once. Hmm.

Seriously though, use the 1:1 ratio and 5-5-5-15 2T timings until you know where your chip tops out. Use the 10.5 multiplier too.
