I'll do it afterwards. - issue not replicated with 1/2/3 GPUs - dual PSU: 1x1000W for 3 cards, 1x 1000W for mainboard and gpu - molex are plugged in - screen corruption are memory artifacts I have this slowdown crash with cards at stock as well. The CPU frequency was stable before (same session, same voltages ...).

It's not the bios ... Pt1t has this issue on an F4g or so. I'm not going to flash the board untill I know what's going wrong exactly. IOH is stock cooling. 1 fan over the PWM connected to IOH

It's not the bios. If it were, I wouldn't have the normal 4G runs.

No, I didn't open a can of worms. All I'm saying is that I've been able to replicate a performance issue present on the UD9. It's an issue, which is proven by the fact that there are also normal runs out there: my 4G comparisons and the other comparison at 4.8G I showed few posts ago. That's why I said I need to look into the problem to find the root of the issue. That early sample board (UDP7 LOL) has already returned to Gigabyte. This is a full retail board. I can make a picture of the box if you want, hehe.

Found some numbers here: http://forum.javaxtreme.org/showthread.php?p=4471 My R3E figures are spot on; no idea why in my 4h testing on UD9 I couldn't get any run where GT1 > 150FPS ...

I agree on pricing ... and performance-wise although I'm stunned the difference is this large. At 4G, the difference is almost non-existing, at 4.8G suddenly huge gap. Must be some other problem, I think. Oh, and ... ehr. I don't think R3E+Xpander is in fact a choice .

Also, as far as I can see the ASUS 4-Way SLI (Xpander) is still not fully available in retail

Quite a lot of mainboards have been sold, as far as I know. At least, relative big amount ... it still is high-end board. But don't jump to conclusions yet. I will re-test UD9 with other settings so maybe I can find why it's slower.

We were discussing the results of Pt1T's testing of UD9 and R3E where UD9 was behind the R3E for quite a bit. In my current testing, I see the same thing happening: Note: with R3E the results vary more than with UD9. Sometimes 151FPS, sometimes 153FPS in GT1, for UD9 it's pretty stable results. I'm now testing the Xpower for some reference 3-Way numbers. In 3-way, the UD9 is slightly ahead of the R3E (although it was different at 4GHz).

Now running the tests on the UD9. Having some weird slowdown issues now at clocks that are supposed to be completely stable.

I'll run the test if Dino is willing to accept a possible outcome where the R3E is able to produce higher clocks ;-)

Hmm. I still have a few drips of LN2 in the tank and already did a few runs on the R3E. [hwbot=1038703]submission[/hwbot] Only thing that's different is the CPU. I no longer have this B1 ES and the one I have is a bit weaker than the one used for those runs. Also, I'm not entirely sure those runs were optimized properly (in terms of driver settings) ... I think any comparison will be open for criticism. In fact, I think the only situation where there would be no criticism on methodology would be when turns out both boards are the same, which is an assumption we can already make now . I can hook up the Single Stage for a few 4.8G-5G runs. Would that be interesting for you?

Well said, Gamer!

This just ran through my head. It's been brought to my attention a couple of times now that HWBOT should set up a separate platform/(sub)forum for leading figures in the overclocking community. As main purpose, this subforum would allow these leading figures to debate on new features, suggestions, problems and so on. In theory, this sounds like a very nice idea, but in practical terms: how would this change the working of the bot? We have a part of the forum (this subforum) that is dedicated to thinking about the future of HWBOT, but very rarely I see leading figures posting ideas on the big topics (eg: hardware sharing) in this part of the forum. How would that change with a invisible special subforum? I know some other forums have tried to set-up this kind of forum (eg: XIP on XtremeSystems), but the true value of that I'm missing a bit. Perhaps ... a visible secure forum would be a better way as it would reduce the amount of badmouthing or finger-pointing for sure, but then it might also reduce the amount of valuable discussions as it sometimes happens that hard words must be said to move forward? Any comments? //edit: by leading figures I don't only mean the people everyone knows about, but mainly the community and team leaders.

The team ranking has been brought up in the last HWBOT meeting (RichBa5tard and myself). Managed to explain the PowerTeam concept and the idea got approved by the software coder, which is already good. Two leagues may not be ideal in terms of maintaining and focus. In the beginning of december an example ranking will be shown on a test server, as well as an actual implementation of the visual aspect of the PowerTeam.

No. It wasn't single channel, so it was sub-par performance ...

The asus-boys have gotten the hang of getting decent 3D boards. The R2E was pretty much the same: CPC a bit more efficient than the other boards.

Surprised in what way?

Hey guys, I had a discussion with Dinos22 regarding the difference in efficiency between R3E and UD9 with multi-VGA and Vantage, so I spend some time testing the boards I have here for scaling. Since this is pretty pointless, I thought I might as well justify the time spent on it by making a nice graph and posting that in a forum for everyone to watch. With a few pats on the back, I might feel a little more happy about doing this ... Conclusion is pretty simple: find a decent CPU and a decent pair of GPUs because the difference in efficiency is insignificant and un-important. Only for 3-Way SLI the implementation of the UD7 and R3E seems to be a tad better, but nothing you can't overcome by increasing the GPU clocks with 10MHz ... (Sorry, no Evga boards in the house so couldn't include SR2 or Classified). CPU: 980X @ 150x27 = 4050MHz UNC: 3.6GHz MEM: 1800 CL9-11-9 GTX480: 800/1050 OS: W7 64-bit Drivers: 259's

I'm considering throwing those out completely. They are not really useful anyways.

also mention CPU type and speed. It matters quite a bit

Nice!!

Also, try XP!
