@510 Fsb using 8800GTS video card, not overclocked...the driver is set to high performance.

next thing to do is slap in my 9800GT card to see any major difference.

Prime 95 @ 500 Fsb

[Ace-a-Rue]

i thought this one, prime 95 at 4335 mhz, was very good just using a TRUE heatsink with a 2.7K Panaflo fan.

[memory]

there is a F5C which is crap at least for a quad core...i heard some results before for a dual core and it was the same...i am currently using F5A which appears to be fine.

Thks for the info. Any linky to this F5c bios? I can't find it anywhere

edit: Ok. Found the linky

[dinos22]

so what bios is the best so far fellas

gotta do some testin soon on my board so i'll just try stock bios and a couple of suggestions here maybe

[BenchZowner]

F4D proved to be the best for me dinos ( for 2GB RAM configurations of course )

i was using F5A and it was good, but, i had a stability problem with my Gskill ddr3-1600 memory (2 x 2gb) at 530 mhz FSB and above...so...i went back to F4H and i was able to run 530 with the 3DMark video benches...trying to solve 540 FSB issues at the moment...i haven't tried F4D as of yet...that will be on my next to do list.

still on F5A

[Ace-a-Rue]

YUP, SS, you are putting the heat on me

i think i am at the end of my road with either the cpu or my memory at 530 FSB X 8...i think it is pushing the system memory a bit to far beyond its specs if i use the 3.20B memory strap...when i take it down to next level, it still acts weird at times...so...maybe it is the cpu cache that is causing the occasional instability...520 FSB seems fine...the only thing to do now is try F4D bios to see if that makes any difference.

Tried F5c last night and it is the worst among the Bios F4d , F4h and F5a.

Failed to boot up at the setting same on Bios F4d, F4h and F5a. Now revert back to Bios F5a.

about the same for me with F5C...it amazes me they even sent that beta out for scrutiny....i know it wasn't for general use but it was NOT even worthy for technical evaluation.

[Ace-a-Rue]

the vcore is getting up there to support this overclock...i ran all three 3DMark video benches...ran 3d2006 first with no problem at cas=8 but i ran 3d2005 next and it froze at cas=8...i re-booted to change to cas=9 and then ran 3d2005 without incident; so did 3d2001.

i am now prime 95 at 4420 mhz...cpu temp is at 77C which is about my limit using actual vcore of 1.425, which is actual droop voltage...idle comes in around 1.45v....i am just planning to do an hour and then consider it a done deal!

everything is at its most furthest point under air; the MHZ is up there along with over-maxed memory speed for the pair of 2gb memory sticks..they are rated for DDR3-1600 but are running at DDR-1664...the only thing i might be able to do to raise the performance is lower some of the timings to tweak a few more ounces of performance out of it.

[kronos]

Just thought I'd drop by and let you know that my new 4 gig kit of DDR3 1600 will be arriving tomorrow. I went with this memory. I'm hoping for much better results. I used to use Mushkin memory alot before I switched to G.Skill so I thought I'd give Mushkin a try again.

[Ace-a-Rue]

good price at a good performance...hope it pays off for you...i do like that 1.8-1.9 range...lets hope for you that 1.8 is the actual working voltage to hold it at 1600 mhz.

[Ace-a-Rue]

my Prime 95 dropped one core after 1 hour and 25 minutes...i guess that i got a little greedy when i said, i would cut it off after an hour...i decided to adjust some of the timings and run it again to see if i can make it to two hours like previously.

Should I start with the voltage at 1.8 and go from there, Ace?

[Ace-a-Rue]

you can if you are going to shoot for 1600 mhz right from the get go...if you are going to accept something less for Mhz then you can try a lower Vdimm...now, leaving the Vdimm in auto might set 1.8 or 1.9 for you automatically...you can confirm that in the PC Health section of the bios.

Thanks for the tip, Ace. I think I try loading optimal defaults and then work from there.

just going to show how excellent this board is and how GOOD is the E8500!...all on air, TRUE heatsink with a Panaflo 2.7K fan running full bore!

[Isaac MM]

Hey guys i will probably get this board as my first mobo, do you think i will have trouble building the system and learning to OC with it?

Also what ram 2x2gb 1600mhz would you recommend for me to use on this board? i will be using a qx9650 btw

wow how loud is that thing

i've never owned a gigabyte before but this board looks good, nice results so far.

[Supershanks]

Great clock Ace, I tried 8x530/540 yesterday but wasn't stable in SuperPi, whichh is odd as i'd hit both previously E8400 4,400Mhz 8x550@3.33D 1,832Mhz 8,7,6,18 Was expecting to get there with a little bit more stabilitty, such as your showing.

you should be fine

i've never owned a gigabyte before but this board looks good, nice results so far.

You've missed out then, I had the X38 before the X48DQ6, that was also good. As I think Ace agrees the board is good out the box & paired up with any wolfdale & ddr3 is great.

it will get a little tricky as you get up into the higher FSB...i would say anything up to about 480 FSB should be a cake walk...once you go to 500, it might get a little tricky for a few of the voltage and memory settings...one thing to remember: i found CAS setting generally cannot be the same as your Static tRead Value (Perfomance Level)...that is not a pure blanket statement...it depends on certain variables where those two can not be equal...i think the lower end of the memory mhz scale you can probably have those equal but as you climb and reach the upper end of the memory sticks designed frequency, i have to separate those two to give the MCH chipset some breathing room in communicating between the system bus and the MCH bus.

if you're new to intel chipsets, intel does not incorporate, as of yet, the memory controller hub on the CPU die like AMD does...Nehalem changes that when it comes out....but for now, this board will not disappoint you.

as for memory, i put a link on the first page of this thread which shows you what gigabyte has tested on this board...read it and then make your selection based on that information...if it says they tested 2 x 1gb sticks, i would say the 2 x 2gb kit of the same classs will also work, so, don't be limited by gigabyte's decision to ONLY evaluate a 2 x 1gb kit....in fact, they make a statement to that fact in the PDF file.

i bought Gskill DDR3-1600 2 x 2gb kit and it works very well...another guy in this thread posted a bad stick(s)problem with the same type memory...so...it can be a bit dubious when one set works fine and another user takes it in the shorts

[Ace-a-Rue]

wow how loud is that thing

i've never owned a gigabyte before but this board looks good, nice results so far.

loudness is relative to the amount of fan noise that you are use to...actually, the 38mm thick 120 fans are generally not to noisy at full rpm...i would recommend to anyone the Panaflo 2.5K or 2.7K fan...it delivers a superior air-flow without a whole lot of decibels...now, if you are one of those submariner-types who like to run deep and SILENT, you might want to take a step back and think about it.

with that all said, i only run full rpm when i do the prime 95 or benching...it makes sense to try to keep the cpu as cool as possible while benching..right!

thanks, Luck!

yes, i had similar problems with this board at and above 520 FSB with all of the bioses running Super PI 32M...it must be something to do with us being at the very edge of memory specs and trying to find the right memory settings to make the chipset and cpu compatible with running super pi...all my video benches were completed but i couldn't run 32M bench get that one

As I think Ace agrees the board is good out the box & paired up with any wolfdale & ddr3 is great.

i agree...SOLID board at a good price!
