Help with my new x5650 overclock

Hello,

I've installed my 20$ x5650 yesterday to hopefully have a little upgrade that would have me good for 1 or 2 years.
I have read some threads about OCing the x5650. But still I have trouble to find my solution.
Maybe you can help me out...

Here's some info:

This is what I used to have:

P6T SE Bios 0908
i7 920 D0 @3.8Ghz on Air (My first OC)
Cooler Master 212 EVO
12 GB triple Channel (3x 4GB DDR3 Cruical 1800)

OC settings: (i7 920 D0)

Manual
21x locked
Intel Speedstep (TM) tech disabled
Intel Turbomode tech disabled
C state disabled
LLC enabled (no vdroop so no pikes and when Idle al lower vcore is used)
Spectrums disabled
BLCK 181
PCIe 100
DRAM Freq DDR3-1451 (x8)
UCLK Freq 1903 (x2 duhh always)
QPI 6532MT/s (x8 I think it was)
DRAM Timing untouched
vcore 1.21250
pll auto
QPI 1.25
Ram voltage 1.64
Everything else auto

Stable and max temps 81 on max load for 6 hours

Now I want to set my x5650 the right way. So Whats is needed? 4 or 4.2Ghz? Maybe 4.5Ghz is max on air if I'm lucky.
Remember I use aircooling and I don't want to invest more money in cooling or whatever.
With my i7 920 I also had patience with OCing. Lowest vcore and QPI to keep the temps low. Screwed BLCK up with steps of 50-100 and see if it was stable.
Best way to have max performance on lowest vcore imo.

I want...

- Have a nice still good enough PC no heavy rendering. I use it mostly as a mediastation these days. lol
- Play some games at 1080p around 60 FPS. I have a option on a cheap GTX 1060 6GB. I think this is max. for this processor?? Again what is needed 4Ghz or 4.2Ghz for gaming experience?

These are my thoughts on OCing my x5650 Westmere-ep model C rev. B1
Stock running vcore 0.960 - 1.128 on default BIOS settings. Under 100% load max vcore 1.184 (x22)

manual
22x locked
Intel Speedstep (TM) tech disabled
Intel Turbomode tech disabled
C state disabled
LLC enabled (no vdroop so no pikes and when Idle al lower vcore is used)
Spectrums disabled
BLCK 182 or 191 (4 or 4.2 Ghz)
PCIe 100
DRAM Freq: DDR3 x4 or x8 ???
UCLK x2
QPI x8 ???

DRAM Timing untouched (9-9-9-24-4-107-10-7-20-0)

vcore around 1.29-1.31 ???
PLL auto ???
QPI 1.24 (same as i7 920 or higher and if needed why please) ???
RAM voltage 1.64 or 1.66 ???
rest auto ???

I Hope you can help me out with some parameters to experience with.
I've read about some issues with the RAM option with the x5650 maybe you can point them out or maybe I'm good with my settings.
I don't see a reason to activate x23 on it. But if you can tell that it would be a difference for gaming... I will hear you.

Thank for reading, if you did ;-)

Kind regards,

Robert from Amsterdam

Looks pretty good. I'd try a higher bclk (190+) at 1.34v, and raise QPI to 1.28-1.30v with freq. set to Auto for stability. That rig @ 4+Ghz. should handle even a GTX-1080, no problem.

I use 200 baseclock with 20 multi. Don't remember voltages, but I could look them up.

Thanks. Today I have time to play around a little.

I can't take it no more!!! lol

Some numbers from CPU-Z at stock/default settings:

vcore 0.960-1.183

Dram NB 2138 / freq 668.1 / 2:10 / 9 - 9 - 9 - 24

37,5 Gflops in IBT

Info on OCing my x5650 B1

manual
20x locked
Intel Speedstep (TM) tech disabled
Intel Turbomode tech disabled
C1E support disabled
C states disabled
LLC enabled
Spectrums disabled
BLCK 200
PCIe 100
DRAM Freq: DDR3 1603 (x8)
UCLK x1.5 - 2x (whatever I try my system only reads 4 GB???)
QPI 7200 something (lowest multiplier)

vcore 1.3250 VTT 1.3250 RAM 1.64 ...These settings I will tune down when I have found a stable good perfomance. Both should be more than enough from what I've read.

DRAM NB 2999 / freq 800 / 2:8 / 8 - 11 - 11 - 28

The problem is that my system only read 4GB ...With my i7 920 DRAM multiplier x8 was fine (was around 15xx) and ofcourse Uncore x 2

When I go to DRAM x4 and Uncore x2 (can't go Uncore x1.5 on the lowest memory multiplier somehow) I get the full 12GB.

Everything the same as above with DRAM x4 and Uncore x2

DRAM NB 2399 / freq 600 / 2:6 / 8 - 8 - 8 - 20

40 Gflops in IBT Only 2,5 higher than stock!

If anyone has some ideas... Please speak and I will try.

Thanks for reading anyway
