The Official X2 Overclocking Discussion Thread

I didn't notice the number of your posts, LOL
I did see some ppl here who aren't XSers, solly ;-)

Has anyone else had trouble with one core of an x2 4400 failing Prime95 while the other core passes? Also, when I run both cores with Prime95 (each using 750 Mb, I have 2 Gb total), core 0 fails within seconds, core 1 is stable. If I test core 0 alone (defaults), it runs for a couple of hours before failing.

The details on my system and BIOS settings are here: http://www.xtremesystems.org/forums/...=80491&page=66

Thanks in advance for any help.

The situation you're discribing here http://www.xtremesystems.org/forums/...postcount=1644 makes it look like it's an heat related problem. One core can't handle the heat both cores generate. Better cooling will probably let you OC further. You max OC depends on the max OC of the weakest core, that's the case with all dualcores.:fact: If your temps get near 50°C stability will decrease very much. Also take a look at this thread http://www.xtremesystems.org/forums/...d.php?t=105295

Thanks, ChkDsk.

That possibility did occur to me, though I had thought it would take more than 50 degrees to cause significant instability. I am somewhat disappointed in the performance of my Zalman, I thought I could get better CPU temps with it. I am sure I installed it right, with a BB-sized dollop of Arctic Silver, fan blowing toward the back, and my case has a 120 mm intake and 2 120 mm exhaust fans, and a mesh panel on the side right over the Zalman.

I have had my eye on an Asetek WaterChill colling kit, I am waiting for it to come into stock, I may have to defer further attempts at OC'ing until I get this installed.

Thanks for the input,

Mark

Maybe it's not your Zalman to blame, but the IHS contact with the core. A lot AMD cpu's suffer (only if you overclock ofcourse, at stock their (or should be) all stable) from bad contact and removing the IHS often makes a big difference. But you can't do very much about it, unless you're willing to remove it (it Ã:banana:s Xtreme systems ofcourse).

I ran a lot of AMD cpu's without IHS, but the question is are you willing to take the risk :)

Anyhow, it probably is heat :p: Get some water ;)

hey guys. can i get some solid instructions on how to oc my am2 x2 5000+ ?
thanx in advance.

The instructions would be the same as any X2 processor such as 4400+ etc all you have to do is read the many previous posts or use google.com don't be lazy.

Thanks

ok i'll try not to b too lazy. thanx.

I don't think I am willing to remove my IHS just yet. I did, however, get an Asetek WaterChill cooling system installed...

I have gotten my oc stable at 2.607 GHz (237 x 11) with my memory on a 166 divider, 1T, timings on auto, but I need 1.52 volts to make it work. While torture testing both cores, temps max out at 44 degrees, a full 9 degrees cooler than my Zalman with an oc of 2.45 GHz at 1.42 v.

My next order of business is going to be to remove the memory divider (other members with similar setups to mine say that my memory can easily do 260 mhz with slightly loosened timings), and tweak with the timings.

My main question at this point is this...as long as my CPU temp stays under 50 degrees, can I increase the vcore some more? What is the practical ceiling for this chip?

Thanks for all your help!

Mark

I am currently at a point where I can go no faster and keep my system stable. I am now at 2750 MHz and do not seem to have a heat problem (I have liquid cooling and the temps stay low). Can someone please tak a look at my settings? Any good suggestions would be welcomed.

appreciate yout help

My Bios Settings

@cc3d, I think this mobo (A8N32) is a f***ing bad overclocker:(
I only found one guy in the A8N32 thread that had some impressive OC with it, all the rest is just for the kids :(

some PC makers like Voodo PC, etc are OCing AMD FX-60 chips (and others) up by 30% with this mobo. I am just now searching the boards for success stories. I sure hope you're wrong.

thanks though

Well, I've been reading XS for months regarding this motherboard, and only found ONE person who OCed over the "typical" 20%.
Can't get full specs from him though ;-)
Either that, or we're all running Prime95 which fails first ^^

2750 on a 4800... less than 15% increase over stock. exactly what i got stable on air, figured if i couldn't get at least 18-20% it just wasn't worth messing with.

no i'm not stalkin ya alfa

Yes, I agree, especially due to extra temps.

Hi, every1.
Assembled the PC yestetrday. Have changed SanDiego3700@2.6 to Toledo 4400+ CCBWE 0608. What the Fu..-only I could say after changing perfect air-cooler Thermalright XP-90C to 745Big Water. Why have I spent money for "water"-to get 2.6GHz again. Second CPU for the last year and so poor with OC. Hate AMD. 250x10.5=2625 OCCT stable with 1.55v. Temperatures-up to 41 Celsius in closed case. Big Water works perfect; while CPU doesn't.
"Death screenshot"-only at 2.75.
I'm totally disappointed. It's time to change horses-from Athlons 2 Conroe.

But 2.6GHz easy with 1.45V. Temp's is 32C idle, and 42-45C full load.

Poland box processor :stick:

Anyone have cpu on this series ?


Sory 4 english ;)

just about the all abovesaid. i suppose, pal, You understand me. People, don't buy long-cached Toledos CCBWE 0608 :( .

I am looking at an eBay X2 3800+ that has the stepping ldbfe 0623wpcw.

I think this is a good stepping? Would it be worth paying £20-30 ($45ish) extra for this cpu over getting a random one?

What might I achieve with stock volts and good air cooling (Scythe Ninja probably)?
Thanks, a quick reply would be great s its finishing in an hour.

couple of guys at our local forum were happy plenty-getting 0617; 0618 X2 3800-both of them achieved 3GHz under water with slight voltage increasing (about 1.5-1.525)

Have a look at this and tell me what you think :rolleyes:
This is my actual 24/7 overclock that I've been running for over a month now, stable as F*** ! :banana:

My CPU reads:
"ADA3800DAA5BV
LDBHE 0601TPMW
T699859A61020
ASSEMBLED IN MALAYSIA"

Take a look here! :rolleyes:

Are the 4400+ 89W good on overclocking? I'm planning to replace my X2 3800+ with this one. TIA!

I just got one of those on Thursday. Currently running at 2.8GHz on stock voltage and stock cooling. I haven't had the time yet to see how far it will go. I reached 2.97GHz on stock voltage when the errors began.

My new X2 3800+ LC...0624FPMW Toledo Core does 2.9ghz at stock voltages and 3.0Ghz at 1.45v.

I think that he makes much more than this, but my mobo maximum HTT is 301 so...


Stay Well ;)

Wow, that's a high OC for a 4400+. What stepping did you get?

Just curious... but how are people finding Toldeo's instead of Manchesters for the 3800 X2?

All I see at Newegg are Manchesters.
