Hello all,

Currently I’m running a custom build watercooled PC with the following hardware inside it:

Intel i7 [email protected], Watercooled
EVGA X58 Classified 3, Watercooled
3x2GB Corsair Dominator GT 1866Mhz@9-9-9-24
OCZ Revodrive 3 X2 240GB
Creative Titanium HD
2xHD6970 in Crossfire@1020/1400
Enermax Revo85+ 1250Watt

The water first runs trough the 2 GPU’s, then cools the X58 and then the CPU, before going into a big XSPC 360 Rad, followed by a big XSPC 240 Rad, and then the reservoir and pump.

I’ve pushed the PC as hard as I could and been running it at those speeds for quite a while now, but it keeps itching to push even further so I wanna learn/know where I could gain more performance, if possible

It’s running on these settings right now:

Multi: x29
BClock: 160.6 Mhz
Vcore: 1.482V@Load
QPI: 3854.7Mhz
DDR3: 963.7@[email protected] (Stock is 933Mhz@[email protected])
NB: 2891.1Mhz

Voltages:
Vcore in BIOS: 1.47500V
IOH/ICH I/O Voltage: 1.600V
ICH Vcore: 1.2V
QPI PLL Vcore: 1.150V
IOH PLL Vcore: 1.815V
CPU PLL Vcore: 1.815V
IOH Vcore: 1.200V
CPU VTT Voltage: 1.375V
DRAM Voltage: 1.65V

And the advice is seek is the following:
1. How much would I gain if I could push my NB towards ~4000Mhz? Alot or won’t it make a huge difference? Also, in order to clock the NB higher, which setting(s) do I need to tweak, because as soon as I go beyond 1,5x Memory clocks it won’t boot atm. Or is it wiser to have a slow NB and fast memory.
2. PCI-E is running at 102Mhz, would I gain something by going another 1~2Mhz faster or is that waisted time/effort?
3. How much would I gain by having memory with higher speeds and/or lower latencies? For example, +2100Mhz @8-8-8-20 orso.
4. How much would I gain if I would increase my BClock any further? Right now the limit seems to be around 166Mhz, but I’m guessing that’s the the chip going beyond 4.75GHz without enough volts. So maybe higher BClock, but same speed on the CPU(Around 4.7Ghz)
5. Is it a good idea to lower my multi towards 28 or lower and start pushing my BClock more, while also pushing the QPI/NB higher, with the memory staying around 950Mhz? Would I gain alot there?
6. It seems that in order ot push the chip beyond 4.7Ghz I need alot of extra volts. Can that be true, or is that because I’m doing something wrong elsewhere and the extra volts are needed to make up for that?

Some questions are a bit basic, I realize that, but I’m really keen on finding out where I possible could gain a bit more of performance(if possible) or if there have been area’s where I’ve been lacking/underperforming in terms of pushing things towards the max.

Thanks in advance for helping me out :D
 
I asked the same question about base clock in a thread
They said run the base clock higher with a lower multiplier
I am running a bclk of 200mhz on my 990x
4.2ghz @ 1.275v

Seems to have lowered the ram temps quite a bit
I still need to mess with it more to see what I can get

My load temps are 60-62c
that is with everything loaded
sli 590s on the water as well
GPU temps are 51-52
