Chew:
help me a bit please, which board? Crosshair IV or MA890FXA-UD7 ? have u some trouble with BIOS? No vdrop?We have in Czech Crosshair IV now, but UD7 not. So, i can still waiting for UD7 or can take Crosshair IV?:) Thx.
MSIMAX possible to take a screenie of the bios settings... my CH IV and Thuban ES only are willing to give me 1900mhz on the rams... tried 4 biosses already... 965BE goes up to 1920Mhz C7 pretty easily :(
WOW, DDR2000 SMASHED :D
MrIcee, does this mean we can expect a return from you?:yepp:
And Brian, do these boards do a "true" CAS6? I remember you telling me that MSI's GD70 was doing well with newer BIOSs and CAS6 because other latencies were increased.
MrIcee has almost fully re-equipped his test bench with the latest and greatest:DQuote:

Much has changed since my days testing on Abit and DFI:) Thank yous to chew* for his insights and assistance. Getting my feet on the ground here and running, tho these fellas clocking with LN2 are beyond my scope right now. I'll be starting with my old custom watercooler and vid card chiller, and also have a 404A modded Prommy. So my results should reflect what the average guy on watercooling can expect. I'm gearing up for 3D too, with a pair of Asus 5870 V2's ready to go.
I'm ready to start having fun again after a very long abscence!
Best regards,
Randi:D
I look forward to your return :D
What's next? OPPINTER? macci? JCViggen (4GHz eight or so years ago)? MickeyMouse (one of the pioneers of LN2 pots)? Tom Holck (Mr. Cascade on drugs)? Captain Cascade? Digital Jesus (did he ever return after being called out about his 01 results or whatever?)? cpulloverclock (he was awesome with 939)? The guy whose avatar was a jumping cat with lasers coming out of its eyes :D And finally you. You were a legend on 462:clap:
Really really good times:yepp:
Leeg those were my runs i'm busy had msi post them for me.Quote:

from my testing the performance at 2000+ is not optimal or where i think it should be but it is faster than my previous stuff at cas 6 at same speed on previous boards so not what i would say artificial......If it was I would not have bothered posting it.Quote:

good news is we ran some 32m on UD7 and iirc 1900 tight was fine.Quote:

well above 2100 at those tight timings.....32m is a much diff story even at 10-10-10 wall was present. Wall around 2050 very simlar to the previous wall i tore down at 1904.....when i have the time I will see if it's a hardwall or a wall that can be massaged past.Quote:

whau, good, UD7 looks simillary as Crosshair IV for OC ?
DDR2100 was benchable but at rubbish timings (non Elpida RAM, it was CAS9 I think). The better controller might be the biggest reason for me to move :D
My head hurts and my MasterCard is begging for mercy. :D The IMC is going to make a huge difference. So far, my best CPU (ES or Retail) is a random 1055T from Amazon that I bought for my son's system and now he will never see it. :rofl: I sent you settings to try and of course this requires some Corsair GTX2 kits.Quote:

In an early beta release, 8GB at 2000 is working but efficiency at 1600 is still much better at this point.

It's Micron GTS @ 2.0v :shrug:
Any reason why the HT link has to be above 2G for better performance?Quote:

I don't recall the bios, it was sent to me a couple of weeks ago. At the time, I had a very small timeframe in which I could test the Thuban using extreme cooling, so I had to go for the best board then.Quote:

If I remember that ratio is more like 2:1 The stock IMC freq. was supposed to be good up to 1066... ;)Quote:

It is an auto rule function in the BIOS, in fact raising HTT (Bclk) above 240 with both NB and HT set to auto will result in both of them falling back to 1920MHz (depends on ratios also), which is even worse, they should stay in sync at 2400MHz until the next auto rule limit is reached. So far, most Thuban processors we have tested will do NB/HTat 2600MHz on safe voltage settings so additional tuning is in order for the tables.Quote:

This will be corrected in the next BIOS but the main reason for maxing HT is to sync with NB speed (which you obviously want as high as possible on this platform) to keep the current memory table at optimum settings. Right now the rules are set to ensure stability/compatibility instead of maximum performance. Now that the AGESA code is stable for Thuban, we will set different rules when the BIOS "sees" performance settings being utilized.
Before anyone says anything, we went through four different AGESA code levels in the last two months or so as the platform and processors were finalized. This is the reason why we had around seven BIOS releases since the ES samples were delivered in early March. ;)
Yes, to truly maximize memory performance, we truly need higher NB speeds to improve efficiencies as memory increases above 1066 on this platform. This is one of the main reasons I like to run NB/HT/Memory in high-sync where possible and why 1600C6 is still my favorite memory setting for everyday use, provided I have a IMC that allows that setting and 3200 on the NB/HT side. I have one right now that will do it on air so I am fortunate. ;)
damn!!!! i want 960T
