theelectic - by clock skew, are you talking about the "DQS Receiver Enable Delay" as reported by Systool?

[AMD-me]

I returned it to Newegg. Going to switch to Conroe.

No - I'm just now realizing clock skew might be exclusive to the 590 chipset. With ASUS boards it's usually called "AI clock skew". With my board it's found under the main DRAM timing controls, with 1T/2T, single/dual channel, etc.

The other thing you might try (again if available) is drive strength. Fire up Systool and see what your default drive strengths are (they're on the second AM2 timing screen) then go into the BIOS and increment them all up by 1 step.

Ruslan, what temps are you seeing after about 20 mins load with your cooling?

[akijikan]

I hit a wall at 3.2GHz, it did not want to stabilize (errors out of Orthos in 9 mins) even at 1.65V and above. Currently stable at 3.13GHz @ 1.6V.

What kind of temps are you getting and what kind of cooling are you using? I thought 1.6V was kinda high. I'm stable at 3.00 @ 1.45V and my mobo sensor is giving temps like 58-63C (I'm using scythe mine air)

I actually have an Asus 570 board (m2n-sli dlx), but it doesn't seem like the bios has a setting for skew. I played around with the drive strength, but it didn't seem to help much. I sent a PM to bachus_anonym who was able to get the board to a 400 HTT in his AM2 testing thread, hopefully he will have some insight.

It stays at 40C after 2 hours

That was with 1.4V set in bios and it failed Orthos, but with 1.45V in bios, its been humming along in Orthos for the last 7 hours.

Exact same as me. 3003mhz @ 1.45 volts...what kinds of temps are you getting?

[funnyperson1]

Actually pretty similar to your temps in the afternoon when my room temp was like 78F, 57-62C. I opened the case and pointed a table fan at it, and temps were 55-59C.

Right now its 45F outside and I opened my window, closed the case, so its running 45-50C, room temp is 19C (66F).

[Skillz]

I keep my home between 68 and 72F, so my room tempature should be pretty good when it comes to overclocking...

[akijikan]

I'm trying...but our unit seems to be losing its touch...struggling to get under 72.

how does the abit kn9 ultra perform? Is it better or worse than the biostar offerings? And how does the 570U compare? Cheers.

[tonster]

i read a review on this board a while back and i remember the reviewers couldn't get a boot with the fsb past 240ish. i'm assuming the newer bios revisions corrected this, right?

i'm thinking about picking up a 3600+ brisbane and was hoping to get it up to around 2.8-3.0ghz with an aftermarket cooler with this board or the dfi infinity.

[funnyperson1]

I think HardOCP was just incompetent. When I first got my 1.0 board it came with the 615 bios (the 4th one released) and was able to hit up to 287HTT no problems.

With the newest 207 bios I can boot at 326HTT and am stable at 316. The only caveat is that the 400 memory divider isn't stable past 305 for me (and a bunch of other people), so its better that you have DDR2 800 or better ram.

[derektm]

I'm looking in the AM2tools program and I do not see the 7 divisor available. How are you guys using it?

What??

[derektm]

What??

Like here:



He has the CPU/7 divisor but in the AM2 tools program when you select brisbane it doesn't show the 7 divisor available.

[funnyperson1]

The am2tools program is wrong. The 533 divider with a 9.5 multiplier is /7.

It is like Mitsubitshi Evo VIII vs Lamborghini LP640 running in between the corner...

No a good example since Jeremy Clarkson has shown that Mitsubitshi Evo VIII could beat Lamborghini LP640 easily when come to cornering...

I personally don't think that its a bad comparison. E6600 runs what 350 bucks? This processor runs 100 bucks. The comparison, was for 100 bucks, it overclocks well enough to keep up with a stock E6600. It seems valid to me.


Its like saying my car, which is 4,000 dollars, w/ 5,000 dollars of mods, keeps up with a Corvette Z06, a car that cost 60,000 dollars. Thats a damn good value, I get the speed and handling of the Corvette for 9000 dollars.

Seems very valid to me.

The Mitsubishi Evo VIII is less expensive than the Lamborghini

Would I need pc6400 ram to overclock this processor to 3ghz?

The dividers work pretty much the same as they do on socket 939 right? Wonder how much performance would be lost with slower ram, since some cheap pc5300 ram is like 30-40 cheaper than ddr2 800.

[funnyperson1]

Yea you can use the 400 divider to get the 3600+ to 3ghz+ without overclocking DDR2533 memory. Only thing is that some people (myself included) have noticed that the Biostar board doesn't clock as high with the 400 divider for some reason. With the 400 divider I was limited to 306HTT, but with the 533 divider I can hit 316-326HTT.

The good thing is that most 533 ram should overclock well enough to hit DDR2 800 speeds with some voltage, albeit with looser timings. I have some of the worst clocking DDR2 I have seen and I can hit 430mhz memory speeds with C6 timings and 1.95V.

Very nice contributions to the topic .Thanks for the 533 divider info
Also tnx to Ruslan and to all that tried this wonderful and very cheap CPU.
Mine arrives on next Tuesday ,so we'll se how it goes
