My AM2 X2 4000 Overclock results

[ItsAlive]

Here are my results from the rig in my sig. Just thought some people might like to know since there is relatively little info about the AM2 overclocks.

AM2 X2 4000+
CCBYF 0615MPMW

Ram is Gskill DDR2 running 830mhz@4-4-4-12 2.1v

Overclock

SuperPI 1M test

SuperPI 32M test

3dMark06 test @ 2.7Ghz, 7900GT @ 525/1800 clocks

3dmark06 test @ 2.8Ghz 1.37v, 7900GT @ 525/1800 clocks

Very nice!

Yeps, a very nice oc. The DSL chips seem to respond better to voltage too.

DSL= DAMN SMALL LINUX chips ?

 

[Corporate Thug]

very nice. this is with the freezer?

 

[Insane3D]

Very nice...I'm hoping for a similar result with my new 4400+ 89W (939)...

I'll also be using ther Freezer...couldn't resist it at $15.

:thumbsup:

What is a DSL chip?

Yeah 2.9Ghz with the Freezer installed. I hit 2.7Ghz with 1.37v on the stock cooler. Temps under Prime95 load with stock cooler was 49C.

I am completely jealous.

I have never been able to over-clock my 4400+ above 2.4 Ghz. As soon as I try 2.5, at 11 Multi, with more volatges on Memory and Core ... it hangs. But it's entirely stable at 2.4. When I see some people hitting 2.6+ with their 4400+ all I can do is ask myself "why oh why".

Very nice OC man, very nice.

Very nice OC man, very nice.

I found that this particular chip only likes a 9x multiplyer. I tried 10x260 with 1.5v and it was a no go. I tried 8x240 with 1.45v and it was a no go also, but 9x323 runs stable as a rock. It may have something to do with my ram not liking the dividers used when running 8x or 10x multis though. I'd try a 9x multi and see if you can get a better OC.

 

[firewolfsm]

nice OC, what's wierd is that my 939 Opty 144 at 2.68GHz get 32 seconds in the 1M test.

By the way, amazing memory OC on that 7900GT, mine only hits 1620, but my core is at 630...I need more bandwidth...memory vmod time?

 

[ItsAlive]

Yeah the 7900GT was a recertified card I bought from Newegg for $200. I am very satisfied with it. I may try a Vmod on the core, but right now its running with the stock cooler so I'm looking to grab an NV5 before I try a Vmod.

I think the low SuperPI times are due to my ram. It tops out at 830mhz.

my 3800 is currently running w/ 1.35v @ 2.72. and a cool 45C under 100% usage 24/7. i have an 89W version. i am also using an arctic cooler 64.... best 15 bucks i've spent in a long time!



nice OC!

 

[ItsAlive]

I'm keeping my 4000 at 2.7 for daily use. It took 1.5v to hit 2.9 and I'm not comfortable running that high of voltage all the time. That is a great overclock on your 3800 chip.

 

[christopherzombie]

I got my AM2 X2 4000+ to 2.66ghz (10*266) with a 1.400 vcore on a Thermaltake Venus 12. It's been at this speed since day #1.

3Dmark06:7233

It looks like our CPU scores are about the same (~20xx).

 

[CupCak3]

also if anyone cares, the board i'm using is a Biostar TFrorce 6100

DSL = Dual Stress Linear. Its a tecnique used on Silicon. Below is a simplied explanation from arstechnica.com.

"Strained silicon works by providing a layer of silicon atoms arranged in a lattice-like fashion, allowing for greater electron mobility. By using the Dual Stress Liner technique, manufacturers are able to etch away the straining materials from areas on the chip where they are not needed. DSL works on both positive (which run faster when compressed) and negative transistors (which run faster when stretched), reducing current leakage and leading to better transistor performance (and ultimately faster processors). "


Anyways, I saw a couple people wondering what DSL was.

That 9x multiplier thing is strange. Have you tried this chip on another mobo? What is the highest stable OC with the 10x? This may be a RAM or motherboard issue???
Also, what G.Skill RAM are you using? Most if not all F2-6400PHU2-xGBHZ will do 1066mhz @ 5-5-5-15 with just a bit more over stock vdimm. Mine will do it at 2.2 vdimm. I just wish I would have grabbed the 2GB kit.

 

[ItsAlive]

My ram is the Gskill stuff with the Green heatspreader. Its the cheapest 800mhz stuff I could find, lol. The highest overclock I could get with a 10x multi is 2.4. I've only had my system for just under a week havent tried any other motherboards.

Gskill DDR2 800

I decided to just keep mine at 2.8Ghz since it is stable at 1.37v and I am well within the limits on the temps. FX-62 BABY!!!!

Very interesting. Thanks for the information. All AM2 CPUs are DSL chips? What about others?

The first chips to be fabbed using DSL techniques were the Venice cores. So ever since then basically, except the San Diego core which just used strained silicon.

FYI, G.Skill naming rule

F2-6400PHU1-1GBNR
I guess the "NR" would equal normal/regular.
IMO, still good RAM for the price, and it can do it with <2.0v.

Hey thanks for the info on the ram. I knew the stuff I got wasnt going to be high performance ram due to the price being so low. I was really just looking to get 800mhz @ 4-4-4-12 timings. On a side note, Newegg raised the price $25 just after I purchased mine so I actually paid $100 shipped for it. Not bad stuff at all. I am curious to know what kind of bandwidth you are pulling with yours at 1066mhz. I get just over 6000 mb/s according to Everest. But thats maxed out at 830mhz and CAS 4.

No, the very first SS with DSL chips are the AM2 chips. AMD said they would NOT be announcing when the process would move to s939 chips. But it appears that the latest s939 chips is using the same silicon as AM2 chips now. The 89w s939 X2's are DSL chips.

Urhh no.

Where did you get that from?

Venice first used DSL, and San Diego first used SS. They were the first cores to use this sort of fabrication and were used on E3, E4 and E6.
