***Official*** eVGA Classified SR-2 Thread

[lowfat]

I honestly have my doubts eVGA will be releasing a successor to the SR-2. They don't have the engineers anymore that worked on the SR-2.

Drawbacks? Last BIOS update was in October 2010. Which sucks, because the BIOS is awful. Include 4 BIOS config save locations, yet only one works at a time. Restart your computer, occasionally lose all your BIOS settings. ZERO failed overclock recovery. If an overclocks fails and you have to reset your CMOS it clears the entire bios including the date and time. Hmm what else, o yes, certain DRAM ratios just will not work at certain clocks. I have to overclock the crap out of my ram, so that I can run 1066 DRAM ratio because w/ 800 I lose have my DIMMs. This isn't even everything.

There is no way I'd ever recommend getting an SR-2 unless you are going to be using it for folding@home where it makes outrageous PPD.

I've had two SR-2s since December. And I can count on my hands how many days both have been operational at the same time.

lowfat,

Great info and many thanks. I may just go to a solid server MB.

It's strange that we see these great reviews, and when it comes to Real World reviews-performance, we realize that it's about marketing and sales.

So far this board has been working for me, Good performer for even the average overclocker like myself

Alot can depend on the components you get...but my SR-2 can do games and fold.

i'm planning a SR2 build very soon, and i have a L5639 and a X5550. Can i run these two together? or will i have problems with this combo? or should i wait and see when SB-E comes in dual socket?

I wouldn't mix those two as they are VERY different in terrms of multi and voltage requirements.
If it was me I'de sell the L5639 and get another X5650..
Best of luck with your build.

[C4PPY]

Thanks MM, but my only question els is; at this point, would it be better to wait for some SB-E/IB dual socket instead?

Maybe, thats your call..
IMHO ain't much that will outdo a SR2 at 4GHz+

Thanks agian MM! You're the man

nope, they don't work together.

Shamino made on Evga forum a special tread for that and on kingpincooling also

[PytonOrm]

why are evga so slow to update any new bioses ? this is very annoying

[Raychem]

I have a quick question to ask here.

I have a chance to upgrade my X5660's to X5670's. Is it worth the upgrade? Besides the speed difference because of the multiplier, how much better is one vs the other?

Opinions please...thanks!

[Chillerzero]

it's not word it, for that 1 multiplier higher.

Keep what you have unless it's a swap..
Both 95w chips, just a simple 1 extra multi on the X5670's and those X5660's will easily do a max speed on air, same as the X5670's..

[Chillerzero]

what a ment

Yep...swap and a bit of cash,

You are telling me. Coming on 6 months now since the last bios release.

New BIOS A54

In the meantime, I have found my 24/7 settings

But my sound goes FUBAR on load

[Chillerzero]

just tested it, no problem with sound.

i think it's you're settings that are not so stable that you loose you're sound.

[ctgilles]

It's FAH, Linx, Prime and IntelBurnTest stable Some other sound problems are voltage related, but I have tried to change the IOH and VTT voltage and a signal tweak (-30) but no success
But I don't want to keep searching because the SR-2 BIOS On average I have to set up in 3 reboots because if I change everything at once it will not reboot and freeze during post (FF or CF etc.).

I have no suspicion that the overclock is not stable. I really don't know what the problem is But I'll continue to change voltages and contact EVGA in the meantime. I don't look forward to an RMA because of all the work involved

Hello everyone. I am getting redy to embark on an SR-2 build. It will be a dedicated folding machine. It may not be a "resonable" build but i want something that will challenge me and be out of the ordinary.

My question is this, does the SR-2 have a complete fit in the Lian Li PC-P80 or is the board a bit bigger than the motherboard tray? In other words, are there enough standoffs on the tray for this board or does it overhang?

IIRC it has a tray for the special extended size of the SR-2, with standoffs for every hole on the board.

[ghstintheshell]

Thank you for your reply Linuxfan. I am also open to anyone have suggestions (with reasons) for any other case for the SR-2. I am also looking at the Lian Li PC-V2120.

[ctgilles]

I bought the PC-P80 "Armorsuit" for my SR-2 build with my Xeons Q3QS, pics are here: http://nl.hardware.info/usersystemen...res#tab:photos

So, I know I could do 200 baseclock but now I'm stuck at 180... So I have to push the VTT (1.35v atm) upwards right? And IOH@1.4v. What's your VTT voltage as I am wondering whether to raise VTT and vCore or just VTT. These ES should be able to do high MHz at low voltage so.

If you don't mind me asking. Did the board fit perfectly on the motherboard tray or was the board overhanging? I am trying to make sure I get a case with a motherboard tray that does not leave post holes unutilized. I'm okay with a case that has a tray with extra standoffs but with a motherboard the size of the sr-2 I do not want any part of the board unsupported.

[ctgilles]

The tray is smaller, but it fits the case. I used the stick-on plastic to support the holes most to the right. However, if you plan on heavy aircoolers, you'll need to support the board from the back with zip ties.
