Thanks to the sideport (Samsung chip). This is my final score, can't improve further. Already shut down the system. But it's pretty cool you can beat LN2-cooled systems with simple air and high ambient temp.

If I had LN2 - yes, but it's pretty hot here now and I can't improbe my previous score 1300+ should be possible with cold.

Maybe I have something better...or not.

Can I use the ROG Pause button on the subcompetition?

No LN2, will have to run it on air. Probably can do 3700 - 3750, but no more. 1200MHz core freezes, needs cold ;p

Excellent as always. I have no GF 256, but will give you some competition in other series (except GF2) where I can't sort out the bad performance.

Another Asrock board that can't clock the sideport past 667MHz?

And I have no artifacts at all Contrary to your situation, this board (came from RMA) is better than my previous one. Old one could "only" run DDR3-1840. But in terms of HT Ref clocking, it's worse. Old one was a champion - 452+ on a DDR3 board.

1.55V set in bios, board overvolts.

Not entirely stupid. Rules are determined by the competition and you're not competing directly for hwbot rankings, you're competing in the "Team Cup". The "side effect" is that these scores also go into hwbot rankings. Yeah, you're sacrificing some MHz because of the screenshot, but you can always continue and make a highest possible validation (on the edge) just outside of the competition. Don't see how the screenshot rule is an obstacle for that. Just ease yourself and use one of the many lightweight screenshot captures, so you don't bother saving it with paint every time.

Tried various lod, I think it was 4.8 for this run. 15 didin't give me anything more.

Strong memory on this card

Don't remember the readings on those caps, but measuring the vddq pins on the mem chips should read the same, no?

I thought they are tied. vdd = vddq here, measured directly on the corresponding pins of the mem chips. Increasing vdd increases vddq as well and they are equal.

It's the same then. Based on the pcb traces and datasheet of the controller - yes, should be the right one. Plus the mem voltage is increasing.

No thoughts on the 97.44 driver? Old thread with screenshots: http://hwbot.org/news/1679_turrican_wins_oc_challenge_of_january_10_challenge_big_success Found this one as well, so I guess it's not allowed: http://hwbot.org/news/1849_update_rules_bugged_driver_rule_elaborated PS: Or allowed?

Btw, 4ns or 5ns memory?

Not sure how much would be the difference if we were using intel cpus. My cpu clock is more than enough, but still can't touch the top scores even with higher vga clocks. It might be my lack of skills, though...

What's up with the low mem clock?

Yes, I know about memory, but this driver is the only one working on my system. I'm getting awful scores with other drivers, something like 100 points below that. Got something like 268 with 66.93 and every other driver I tried. Don't know if it's something AMD specific. Otherwise it's true that these cards are limited by the memory subsystem. I've managed to clock the core to 360MHz on air, but struggling with the memory. It even gets worse with more volts. I saw you have attached wire to fb1, so I'm going to look at the datasheet once again, maybe there's something I'm missing in my mod. And the performance is not good either. No way I can reach your score with the current situation.

Great score. Id on't know how you guys pull out such good scores. My performance per clocks is awful

Same here with my nLighted XP.

yeah, 7.5GHz on air and 880G chipset. Another reliable guy.

I have to bring out the old question about bugged driver 97.44. There are some submissions in the rankings with that driver and the question is if we are allowed to use it in the competition? It's either we all use it, or nobody uses it. Equal playing field and so on. If I have to vote, I'd say no, but don't want to be beaten only because someone used it and I didn't. Wanted to say it at least for those who are not aware of this. I know finding the right driver is part of the fun, but for gf4 it's obvious which one gives highest scores.

Which bios version? I'm running 0905. This is by far the most stable for my board and I don't want to change to newest, cause I can't revert back.
