8GB w/q6600 vs 8GB w/e6750 and IP35-E

[Tweakin]

Between the Q6600 and the additional memory, I'm having a hard time just getting my system up to 3.2GHz now. I have the memory set at 5-5-5-15-2t and tRfc is at 52.

I haven't changed my gtlref yet as I haven't found any good factual information. Lots of "do this" or "do that" stories but no real information yet that makes sense.

All other settings are identical when I Primed my system through 3.4GHz:

vcore: 1.3325
mem: 1.85
Load temp: 67c (stock intel POS HS)

 

[GuitarDaddy]

Have you tried bumping the vdimm and or NB volts?

I have heard reports of people having to bump both to get 4 sticks stable at same clocks

 

[Tweakin]

I moved the vdimm up to 1.85 from 1.8 to start with. Little steps.

 

[Tweakin]

I passed 1 hr of orthos at 3.1, so now it's time for more:

vcore: 1.3325
vdimm: 1.85
vtt: 1.27
MCH:1.29

I'm currently in windows at 3.2 and running orthos now. Temps are 69c loaded but it's also really hot in this room...79 degrees.

I had a similar experience going from 4 to 8GB. I was rock stable at 3.71 GHz (8x463, I believe), which I think is pretty much the max for an e6750. Then I popped in another two DIMMs. Sure enough, I had to throttle things back a bit to what's in my sig. I've got no complaints, though.

At some point ITNTDF, I'll grab an e3110 or e8400 but the cover ain't coming off this case for awhile.

Had that problem running 8gb getting stable, took out 2 dims and then found out while my Patriot memory was great for running my E6600 @ 3.2-3.6 it did not like my E3110 at 3.9-4ghz it just refused, switched to crucial got stable at 3.9ghz. With 4 dims, then one went bad so I took a kit back and put the other in my brothers PC and bought 4gb of G.Skill DDR2-1000 and this memory is much more friendly to 4ghz+ oc's which I'm running right now 4050. 780i and my E3110 want a lot of voltage above 1.4 to see 4ghz+, I would move to setup a wc rig if I hadn't just fallen in love with my Noctua NH-U12P load temps low to mid 60's.

 

[Dadofamunky]

Yeah, my guess is that with the northbridge being what it is, it's just more demanding on the system to run 8 GB. Even if I got a 3110 or 8400, I doubt I could hit 4 GHz in my current system. When the Nehalems come out it'll be interesting to see if their IMC makes that problem go away.

Still and all, I'll trade 200 MHz to have the extra headroom for SuperFetch, Photoshop and a pretty much unlimited application space. (And having four of those lovely blue RAM sticks is pretty appealing to the eyes.) This thing is sweet. I'd only swap CPUs to get the temps down a bit and for the bigger L2 cache. Not sure how much the clock-for-clock increase bet. a 6750 and an 8400 is.

I've read both ways on whether one needs to increase tRFC further for 8 GB. My board lets me; when my second set of sticks arrive I'll let you know.

Meanwhile, if you can set it absurdly high, try it to see what happens.

From: 4x2048 Gbs DDR2 800

8GB 4-4-4-15...i think you may see some issues....have in mind this is a HUGE memory load.

Try 5-4-4-18, tRFC 195ns, rest auto's 1.85V to start

Dadofamunky & bfdd:

Going to 8GB on a quad gets a little more intense as the demands really start to stack up...Having just come from an e6750 I can say that a quad is more demanding on the board. My vdrop and vdroop have increased to fairly intense levels:

bios............windows idle..........windows load (Prime95)
1.3525............1.320.....................1.264

As for getting the Quad stable, I'm in windows @ 3.22GHz now and Priming for some time. Will post more results as they come.

Tweakin, remember this post?

With temps like that I'd bump up the NB voltage a little and see what happens...maybe it's your memory that's holding you back.

3.2 is nothing to sneeze at for a quad though...that's still uber fast.

This is with 8 Gig of ram and I am still tinkering with the timings. This is definatly a learning experiance with 4 x 2gig sticks. BTW, using Geil @ 2.0v. They have a range of 1.8 ~ 2.1. I will keep you posted what my settings are as compaired to yours.


GA-EP35C-DS3R Q6600 @ 3.2 Geil Memory

 

[Scotteq]

8GB of 800 Mhz OCZ Reapers here:

DFI LP UT P35 T2R mobo
4-4-4-12, 2T, tREF 54, vDIMM 2.1v <<=== {Top end of rated voltage, rated timings, else is Auto}
400 (1600Mhz) FSB, so 1:1 on the memory divider
Q6600 - 8 Multi - 3.2 Ghz
FSB @ 1.33v <<<==== {up 3 10ths from Auto}


Agreed with the suggestions on bumping the voltage to your front side buss.

 

[Tweakin]

I've been running Prime Stable for several hours now, but I have made many adjustments. It's very time consuming...raise this and lower that...etc.

 

[Drsignguy]

I feel your pain there tweakin!

you need to flash to bios 16. that helped me tremendously with vdroop. crank up mch to 1.37 or 1.41. make sure that all your case fans are on medium. Can you install the side 120mm fan with your scythe? I couldn't do it with my tuniq...

I already flashed to v16 some time ago, and that cured most of my vdroop with my e6750. As for the MCH, I'm sitting at 1.29 and I raised my GTLref to 70%. I also had to bump my VTT up a notch, but with the current Intel Heat Sink it's just putting out way too much heat to test.

I'm thinking about putting my e6750 back in and letting go of the quad. I'd rather have the higher colck speed and additional memory then 4 cores heating the house...time to be deep in thought. (smoke pours out of ears...)

That's a BIG vdroop. Amazing.

Yeah, I can totally relate. The CPUs are just so stonking powerful that even Intel's chipset guys are hopelessly behind, as are the mobo guys in general. I recall with my Athlon X2, it was really hard to run with 4 RAM sticks at all in most motherboards. But 4 cores and 4 stix? Yeah, I totally get it. I wonder if the newest Striker Extremes and stuff like that are built to eliminate those issues. That would explain their price tag.

Makes my temptation to get an e6700 a bit more difficult... That 10 multiplier is VERY tempting...

 

[Drsignguy]

I feel the pain that Tweakin is going through. Only differance is that I wont sell the Quad, Getting the Q6600 @ 3.2 isn't the problem. Have it stable and ran OCCT ( 8 hrs, CPU infinite ) without errors. The problem is the 8 gig of memory. Just cant seem to get it stable ( yet ). Adjust this, adjust that....Hmmmm what a PITA!:disgust:

I agree...it is the memory. But I would rather have the memory with a dual core @ 3.6 then a quad at 3.0. I don't do any video editing or Photoshop work...so a quad is a joke for me...I just couldn't help myself at the current price...I had to try it out.

I need to see if Bryan needs another quad

 

[kkk60091]

For 8GB -GSKILL F2-6400CL5D-4GBPQ, GA P35C-DSR can take it without a voltage increase anywhere.

ASUS P5EW PRO also can take it without voltage increase.

GA X48-DQ6 need 0.35 increase on MCH to be stable with the same 8GB ram....

switch to 8GB Mushkin, GA X48-DQ6 need 0 increase on voltage.....


try to swtich brand, you may find something good...

I like my GS Kill...works fine. The issue is not with the memory, but the amount load and how that changes the OC. I run my memory @ 1.85 and the quad at 3.0 GHZ with no voltage changes at all. The problem is that the cpu now would require alot of voltage if I wanted to get back up to 3.5GHz like I was with only 4GB, and I'm not about to put more then 1.4 vcore into the cpu...

 

[Drsignguy]

Well after many attempts, I have taken the words of wisdom from Tweakin, "it is what it is" I have tried to accomplish the ever so daunting task of getting 8GB of Ram stable @ 3.2 and to no avail, even though I can get the Q6600 stable @ 3.2. I did read the threads in here about tFRC and made adjustments but still same results... So, I have dropped to 3.0 with a VID of 1.3250 and vcore set to 1.4000v in bios, adjusted settings for Ram (if stable, will post settings) and is running Prime95 for 40 minutes now, so far, so good. With a high VID and Max Ram, seems to me a high hurdle to leap over. Doesn't mean "it" can't be done, Quite a bit more difficult to achieve. I will continue but, Not today. I did however "Lap" both cpu and Tuniq and I am happy with the results. At least my temps are good.

I'm thinking of lapping my E3110 and my Noctua NH-U12P, I have all the stuff just hmm need to do it lol =)

Hey, If you have the proper materials to do it , Git er done. If I can do it, I know you can. I just followed Greysky's advice. Besides, if I can't have high Ghz, at least I can have low temps!

I jst ordered 8GB of OCZ Reaper 1066MHz for my Striker, we'll see if the 300$ board does better...

 

[Drsignguy]

Yeah, keep us informed as I truly would like to know. I would wonder if the higher Mhz would be a less stressed issue for the mobo. Or if the Ich is just plain stressed out due to the amount of traffic it receives.
