Hi,

I'm running a 4930 now, on my RIVE all under water. Note the 32Gb RAM...

I can't decide if I want to under clock my RAM to 2000mhz to use the 125 Strap with a 36 multi or use a 44/45 multi to get 4.5ghz and run my RAM at 2133mhz.

Just trying to get the temps and the speeds where I want them.

Do you think that 4.5ghz is a reasonable overclock? or should I set my sights a little lower for basic use?

When I'm back home I'll show you what my current BIOS settings are

Have you looked up 8packs x79 ocing guide he helped me lots?

Yeah, I just haven't done much with the straps before...

The main reason I'm asking is because I was using 36x125 until I changed my ram...

I can't push it to 2400 as 8 dims just won't stay stable at that!!!

Just working on getting a stable OC on the 100 strap then, with 2133 ram
 
I'm having real problems getting a stable overclock on this chip; not sure if it's the bios or the chip tho!

I can up the max multiplier, but if I don't turn off turbo it will blue screen on boot 90% of the time... even with CPU @1.4v
And if turbo is off it will only run at x34 not 44... this is on the 100 strap as well.
 
8 RAM Modules (with the additional power supply in the motherboard)

RAM timings are 9-11-10-27-2.

Running at 1.725v (Should, in theory run at 2133mhz @ 1.5v)

VCCSA & VTT are both 1.15

Running at 100BLK, 46x @ 1.35v

If I run Prime95 it's stable so long as I don't run the "Blend" where it falls over very quickly, so it appears to be a RAM issue.

Should I look at loosening the timings? Or is it just a case of not enough voltage? Up VCCSA & VTT, or raise the RAM voltage to 1.75?


The problem appears to lie with the 8 DIMM's as most people are having no problems with 4...

Yeah I know, I was mainly running prime to figure if it was the CPU or the RAM

I don't really do anything on my rig that will really stress test it!!! haha!

I guess running a couple of bench tests would help; I can't believe the temps I'm getting tho.

Running at 4.6ghz @ 1.35v I'm getting CPU Temp of 19c idle, and CPU Package of 30c.

Under full load for half an hour no core was over 60c and the package was 63c, CPU 50c.

Unloading the CPU dropped the temps back to 1-2 above idle in 4 seconds!!!
And my D5 pump is only running at around 50% power.

Yep, that appears to have mostly done it I think...

I've upped the RAM Voltage to 1.73v and the VTT & VCCSA to 1.25v

Prime95 still kills it at 46x multi, but I'm going to start with some light gaming this evening and move up from there...

I need to shift the thing out of the kitchen first and it's a leviathan!!!
 
It's 2 kits of 4x4GB Corsair Vengance GT 2133mhz

CMT16GX3M4X2133C9

Tested at 2133mhz @ 1.5v
Tested Latency 9-11-10-27-2



I'll take a look at that this evening Rroff, while I run Real Bench.

Hopefully I can get ROG connect running to pull the live data off on my laptop, while running it, so if it does blue screen I should still have the data!
 
the only 2 timings available on the 125 strap are 2000 or 2400

So it's going to end up being er... whatever the 2000 one is at 129; which I don't recall off the top of my head.

I did have it running on the 125 @ 129, but I switched back to the 100 strap to see if I could get the timings closer to 2133mhz.

If you dont use progs that really stress your PC. Why do you need 32gb of ram then. Get rid of 16gb that you dont need and raise your clocking.

Haha, I can't do that... it wouldn't look right!!!!!

The blocks end up either overhanging the CPU block, or not over the DIMMS properly (as in you've only got support in slots 1 & 3 not 2 & 4 so there is a larger over hang on one side than the other...

It was an acestics choice rather than a requirement choice.
 
Right,

I got it stable @
4644mhz (36x129) @ 1.325v
RAM @ 2064mhz (9-11-10-27-2)
RAM is stable at 1.75v, lower can cause some instabilties.

(This does show in AIDA64 as 1.74v, but I don't think that's too much of a problem)

Core Temps are around 63c when hammering the system.

Gaming leaves core temps around 35c-40c

I can get it to boot at 37x multi, but it bluescreens, even at 1.4v so I'm not really sure if I'm going to get much better than this at the moment.

Here's where I'm at right now:
 
Command rate 1 is a little unstable, can I loosen any of the other timings to improve this?

It doesn't blue screen, but things aren't as stable as they were, and pi fails after about 3 seconds!
