what I have noticed is that if you change your FSB over 1495 the Ram suffers a huge drop in bandwidth amd huge latency increase, and also can anyone link bios 1301/1302?

I'm interested in the 1301/1302 bios as wellQuote:

Well I don't know what happened there, but I got an error when I was running prime95 too... so I went back to an old image of my OS, and tweaked a little in bios. Had another go for 3.6GHz too, but didn't get anywhere so went back to 3.5GHz and ran 3Dmark again. This time I'm getting benchmark score more like I was getting before with 4GB of RAM. 43153 was my previous best averaged score, and I'm now getting 43050.
Also checked my video drivers, and they're the latest available as far as I can tell.
I just need to tighten the RAM timings, which are a little slack at the mo.
Are there any rules when it comes to RAM timings? Right now I've got 5-7-7-23 @ 1000MHz. Was going to set 5-5-5-15, see how that is, and then perhaps take them down a notch from there, then test again. I'm just running a prime95 torture test before I try anything else.
well I have my OCZ 4GBs running @ 1080 and timings 5,4,4,10,

nice - not sure if my PC2-8500 would handle those timings though!
I'm using the 1301 Bios.
Only change I see so far is that Auto works for Vcore now up to 1800.
Still waiting on RMA, though it wont be much use... no where to use it.... never mind, figure something out.
hopefull new board and new bios will be just the thing if I see my computer again anytime soon.
Well, I just, after three months of trying (built this rig in February), finally attained greater than 20,000 on 3DMark, with a score of 20,015 :toast: :party:
I had to put new ram, a wd raptor, ram cooler, nb and sb coolers, a cpu cooler, and akimbo coolers on the vid cards to get there, but I got there.
I attained it with everything overclocked to the nuts (E8400 @ 4.5). My normal daily wattage is ~215 to 230 watts, and while running the bench, it reached over :caution: 415 watts.
Congrats on hitting 20K man, i just did the same thing with my setup:D.Quote:

damm, this board is like the first board that I can overclock the FSB over 1900, but sadly my CPU getting to hot so I think I may need to go water cooling for some soild results, and this ram latency problem keeps bugging me
holystarlight
I have noted that a huge decrease in bandwidth and increase in latency occur at 450/451 FSB (1800/1801 Clock Freq). The ram latency bugged me too, but as per my previous post, I just went ahead and brute forced my CPU at 4.5 ghz to get my new high 3DMark score.
I have made 2000 FSB with the Zalman 9700LED and the CPU doesn't even reach 60c under load. What's ur CPU?
Has anyone with a Quad made 4k with air? If I remember, 3.8 is about max.
holystarlight,
you could always try doing this :D
Using a Q6850 (G0), I can get 4Ghz with 450 and Multiplier at 9 vcore 1.5, and temperatures range from 66c to 70 every core on full load and idle at around 37-43 on every core. so just have to wait untill I get watercooling to push it real far, because those temperatures on load are a bit to high for every day use :P
also using RealTemp 2.5 for temperature readings.
EDIT: just tried again to clock my CPU but getting to hot and is yelling at me to get a watercooling system, not going to go over (vcore) 1.5v :(

what do they call that btw? I remember seeing it long ago but been dying to find out more about it but couldn't come up with anything.
It's called "lapping"Quote:

I don't appear to be having bandwidth issues over 1800fsb. Ive had this board 2 days 1301 bios. Still tweaking i'm sure i can get a little bit more. I havent touched mem timings yet since initial setting to 4-4-4-15. This OCZ 4x1gb is rated at 3-4-4-15 @800.Quote:

With this mobo, can i run the vista64 DVD and see all the drives without needing SATA drivers?
This board will also run with 8GB DDR2-800 ?
Is it flaky using Vista64, eg. Install finishes then first run get a BSOD or some crap like that.
Yes you will see the sata drives during setup. RAID drives show as well.Quote:

using 4gb ddr2-1142 dominators @ 2.1v

I don't get it, you guys dont seem to be having a problem with the ram bandwidth latency going crazy when you up the FSB, maybe its something to do with the Kentsfield CPUs, when I get home I will post some screenshots of the problem.Quote:

What are you benching in winrar?
I have not tried my q6600 in this mvb since getting an e8400 but I can almost match the 600mhz doms with $84 A-data ram at 540mhz with 4GB. 11207MB/s.Quote:

If I get the time I will try the q6600 as it will run 450x9 to see if the bandwith drops.
