Sb memory bandwidth is so much higher than x58, so tempting

but 4GHz is a rather conservative for Sandy OC. Quite a number of them can even go for 4.5GHz, even most can do 4Ghz on stock.

Load line calibration is on default = auto.

Turbo ratio is 40, same as my Multiplier. so it shouldnt OC further.

give ur proc a few bumps on vcore, dont compare with others doing 5 GHz @ 1.36v bcoz each proc has its own strength and behaves differently

For MSI P67A-C43 and MSI P67A-C45
BIOS V1.9b2

Found some Transcend aXeRam DDR3 2400MHz 9-11-9-28 in stock,almost same as CMGTX3,use "Powerchip" FBGA chips.
What you guys think?

Guys, here's my setting, hope it helps you guys. Here's my 1st try on undervolt overclocking, currently quite stable for a moment, if anyone interested what OS that i'm using, i'm currently using Windows 7 SP1

Asus P8P67 Pro, BIOS 1305 with 2600K + Hyper 212+

Asus UeFi settings

Ai Overclock Tuner - Manual
BCLK/PEG Frequency - 100
Turbo Frequncy - Enabled
By All Cores (Can Adjust In OS)
Turbo Ratio - 40

CPU Voltage - Manual Mode
CPU Manual Voltage - 1.160v
CPU current capability = 100%

Non Load Temperature = 35c
Max Load Temperature = 51c

need some guide here for a newbie, I'm currently using 2500k+GA-P67A-UD3, previously OC to 4Ghz using stock heatsink. But recently I just brought CM V6GT and try to overclock it to 4.5Ghz, Vcore at 1.35. Supposedly working fine, but after few hours of gaming, it would crash into bluescreen, dumping memory something like that, seem like it still not stable .... any advise I could use ?

Pls refer to bsod codes listed in my 1st post.
U wil know what to do

think its worth a shot if the price around RM350

price stated there overpriced.

Cex price for Mach Xtreme Armor X DDR3 2300C8 it's also RM515.
aXeRam 2400 cost arround RM570.

i7 2600K @ 5.3 GHz
2x2GB Corsair Dominator GT 2000C7 @2133Mhz 7-7-7-20

0x124 = increase/decrease QPI/VTT first, if not increase/decrease vcore...have to test to see which one it is
My vcore already bump to 1.35 instead of 1.34, still having the same issue, but the length of "survivability" was longer ..... still need to increase ??

124 is related to insufficient vcore.
U should try a higher vcore say 1.45v if stable then only reduce it slowly notch by notch. Worst voltage comes 1st.

Omg owikh 5.3G jealous la. Is that linx stable? Temp wise?

With that insane vCore, dont think i will bench 5.3GHz right now at this hot place. So far linX stable max out at 5.1 GHz HT only, cooling limit. The Elpida 7-7-7-20-1T is meant for short tests ie Pi 32m only. Not to be stressed, 1.72v vdimm btw...

IC, max temp for 5.1 linx?

Check out the 1st page

Maximus IV Extreme -UEFI 1204 BIOS

http://www.mediafire.com/?qvgxf3wa6wv115a

- Improved OC performance using Multipliers or Auto Overclocking
- Improved BCLK and DRAM OC capabilities when enabling the “Internal PLL Overvoltage” option in BIOS. Note - Sleep/Hibernate will not operate properly due to Intel Specs.
- Improved Memory Profiles and Performance (Elpida Hyper owners, please use Red Slots for best performance, CFG Lock to Disable should improve SuperPI times even better now)
- Improved USB compatibility, performance and UEFI fixes
- Minor Bug Fixes
- Enable SPDIF output support in UEFI
- Enhanced auto rules
- Fixed OC profile usage with vCore offset mode
- Enable CPU target frequency at POST

Hi , just wonder whats the NB and SB temp for those p67 ? Been using x58 for quite sometimes and those x58 is really hot, need to wc to cool it down.
