EVGA 680i RAM compatibility

[mnemonik23]

Please share your success / issues with different brands, types, speeds of RAM with EVGA 680i here.

I've seen users reporting problems with G.Skill PC-6400 - No system post.
Could be the same problems as with Asus 965/975 boards and need to use a "slower" stick of DDR2 RAM first to post and then replace it with new RAM and change options in BIOS.

Please iclude the following:

had problems with my Corsair 6400C3's and my OCZ Titanium. Got it to boot once and changed the voltage no problem.

Did you have problems or not?
BTW, This board is by far the heaviest board I've ever lifted. :laugh:

 

[jreg]

My board is on order, it should get here on Tuesday. I'm trying it with some PC6400 OCZ Gold memory I had sitting around. I'll post my results then.

Whew!!! OK...so the 6400C3's are "good to go" right?

What did you change your voltage to and at what timings?

I've been looking for someone else with the 6400C3's and this board as this is what I have. In reality the 6400C3 are the same as the TWIN2X2048-8888C4DF's. As I understand it the difference is in the Dominator heatspreader.

Dominator are higher binning of the same ICs. You are guaranteed 1100Mhz out of the Dominator and nothing over cas3 DDR2-800 in the normal version.

In other words you can RMA and have the Dominator sticks replaced if they do not meet the advertised speeds. The normal Twinx series is not guranteed to do those speeds.

If you investigate the evolution of Corsair's 6400C3 memory you will see that it uses the same IC's found in the Dominator TWIN2X2048-8888C4DF series. The higher speed guarantee in the Dominator memory is a result of the new cooling "design", a wee bit of marketing and a little bit more volts. Using the same IC's and the new cooling design Corsair found that they could reliably push the memory to new levels.

Adding the new marketing spin, ie., cooling fins, in addition to 2.5v allowed the same IC's to run at the highest Dominator speeds. Corsair also claims to have added copper traces to help with cooling in the performance Dominator memory. We do not know if this was done the to 6400C3's.

My point here is that the IC's used in the 6400C3's are the same found in the 8888C4DF's.

No, it's BINNING. Basically the hand pick the ICs for dominator and toss everything else in lower lines. That's why you're not guranteed those speeds. Every manufacturer does this.

it's similar to how they bin CPUs. Say a E6400 is tested at rated speed and doesn't pass whatever testing they do. It's binned as an E6300.

You fail to see my point. Let me put it this way. They are no longer BINNING for the 6400C3 line but instead using the best IC's for the Dominator line. What once upon a time went to the 6400C3 line now goes to the high end Dominator memory.

Hope that helps.

Looking at getting a 680i also. Keep updating this with known good working recommended ram.

That's incorrect. I've talked to a few people who got something other than Micron ICs in their Twinx6400C3s

 

[BoboKatt]

Will be trying it soon with Ballistix DDR2-800 4-4-4-12 2.2V on the eVGA 680i
Will add to this post as soon as I have it all set up.

 

[NYHoustonman]

Bought 2x1GB of OCZ platinum, DDR2-800, which was on sale at newegg for 220 after MIR (still is I believe). I haven't had a single problem (and for the first time in my life I was able to install Windows without removing a stick of memory, strangely enough).

Uses Low binned Micron D9GMH more likely than not. Depends what revision you got hold of, but good you're not having issues.

Anyone looking at memory should checkout the Crucial 10th anniversary DDR2-667. I've seen people run them to DDR2-1200 stable (not 24/7 obviously). And many people run them at DDR2-1000 24/7. They will do DDR2-800 at the rated timings at 2.2v almost guranteed (give or take depending on other factors).

From what I hear Crucial usually doesn't bin their ICs from Micron very much, but the 10th anniversary ICs were binned (not as high as other manufacturers do) so it's a more selective memory than the usual ballistix.

 

[imported_duenorth]

seems like Corsair memory are more sensitive then most. I had that problem before with an Intel board (yes, I know it sucks). looking to find out more about the EVGA boards since they are pretty new to the scene.

That's nice, I got an eVega 680i and G-skill 6400 coming next week.

SOunds like an issue in the BIOS not recognising the timings properly and setting the voltage incorrectly for the low timings it tries to run.

When I first booted my P5B before updating the BIOS it set my Corsair to DDR2-533 3-3-3-4 at 1.8v and it wouldn't boot past the post screen.

 

[jreg]

Ok, the modules I have are OCZ PC2-6400 Gold (OCZ2G8002GK). They are rated to run at 5-5-5-12 at 2.0V.

I have 2 1GB sticks, and one works better than the other, if you can call it that.

The "good" one is able to pass memtest at 2.1V running at 533mhz with 5-5-5-15 timings. Lowering the voltage to 2.0V or increasing the frequency to 667mhz iat 2.1V results in instability. The other stick won't even do 533mhz at 2.1V without errors/lockups.

So definitely stay away from this memory for this baord.

I've actually found that I have the same issue, but memtest fails at the same point every time with both in (not at all with the 'good' one in), so I know (I think) one of the sticks is bad (also tried using different slots, still instability)... Gonna be RMA'ing it ASAP.

So crucial 10th anniv RAM is a good bet on this board?




Off Topic

What is the highest eVGA video card you would consider running on this board (not including the 8800 series)?

If I remember right, I read some people on xtremesystems using that memory.

I'm not sure what you mean by your video card question. It will work with everything from a 6300LE to a 8800GTX so I'm not sure what you're trying to ask?

I do not want to spend the $$$ for the 8800 card right now. However I do want one of the other top of the line cards. I'd like to get it from evga so that I could use the step up within 90 days if I decide to go to the 8800 series. So I am curious what the best card is besides the 8800 series that is available now. For example I know the 7900 GTO is a popular choice but it isn't available now.

oh i understand now

Try ths 7950GT http://www.newegg.com/Product/Product.asp?Item=N82E16814130066

I'm sure you can find a better price too if you look. Also look at the 7900GT

hahha. i actually ordered that one earlier today. thanks though.

 

[de8212]

I ordered the 680i along with 2GB crucial 10th anniv, the 7950 KO overclocked card and an e6400. Corsair 620 watt ps.

Any problems with anything?
