Core i5 Overclocking and Feedback

Boneface · Oct 14, 2009

LOL Glad someone posted here, i couldnt find the topic when doing search.

Just got mine last Friday.

i5 750
Asus p7p55d
Ocz 2x2gig ddr3 1333 Plat edt.

Still figuring out how to OC this thing right, Lots in the bios i have no idea about lol

Some P55 MB may have sub par material in the sockets which get super hot and damaged when over clocking.

DanishDevil · Oct 15, 2009

Bad juju for Foxconn 1156 socket owners. Check your sockets guys. If they're Foxconn, call your motherboard manufacturer and bitch the hell out of them.

4.0GHz is stable 4.2GHz is benchable but I cant run the ram at 2000MHz with cpu at 4.2GHz, damn GSkills

Easy board to clock tho once you learn how it behaves, was able to drop alot of volts after learning how vCore and IMC behave together

200x20
CPU Volts: 1.35
CPU PLL: 1.80
IMC: 1.39
PCH: 1.046
Dram: 1.65

Ok is it better to have higher Mutli x lower bus/blck speed or the other way around?

thanks
Boneface

DanishDevil · Oct 16, 2009

It has always been better to have a higher bus speed because it makes everything else work faster as well.

Look at it this way. Everything in your PC works off the bus speed / blck. Your processor and memory use multipliers to determine their final speed. It is best to find the happy medium for your memory, though where it's pushed to its limits.

That HK looks stellar!

thanks, its the Nickel plated version from sidewinder
Joel did a great job plating it.... I machined the 1366 mount to 1156 specs and am very happy with the results

214x19 (4.06GHz | 2140MHz DDR3) @ 1.38v was the sweet spot for me Grnfinger. Kept my temps in the low 70's during load. What are your temps with the water setup?

SK-1 · Oct 17, 2009

Subscribed, Gigabyte GA-P55-UD6 on the way. :toast:

Idle the core's all sit around 28c
Full prime load they top out at 62c with ambiant around 20c
I have LLC enabled so vcore hits 1.36 under load, might play with disabled this weekend

Still having trouble getting the ram to run at rated 2000MHz stable

Nice keenan

i750@3.67 (173*21)
Asus P7P55D Deluxe
4x1 Kingston @ 1384MHz
vCore 1.25
temps while playing Risen in HWMon ~73oC,while SpeedFan shows ~57oC
dunno what is the real temp dou :/

DanishDevil · Oct 22, 2009

Use RealTemp.

keenan · Oct 22, 2009

Realtemp 3.30

johnnyfiive · Oct 22, 2009

Yep, Real Temp is my fav temp monitoring app. That and the Intel Gadget.

Looks like a pretty nice chip keenan. What batch#? Vtt?

Turbo enabled overclock with C-State and C1E

I was doing a similar overclock on my X3440 and thought I would give it a try on my i5.
1.375v vcore set in BIOS with vdroop (LLC disabled) 181x21 turbo enabled (4 threads) and 181x24 (2 threads) with C-State enabled. In effect you get a 4.3Ghz dual core and a 3.8Ghz Quad. If you want to try this type of overclock I would recommend leaving C1E disabled at first to dial in your voltages for stability. With C1E enabled your voltages can drop quite low (0.988v) and will spool up on demand. You do need more vcore to stabilize the x24 multi then is required to run 4 cores at x21 multi. In my overclock at 3.8 I'm showing 1.352v/1.364v load in CPUZ. My board overvolts with C1E enabled and will show as high as 1.399v/1.411v in CPUZ while running SuperPi 1M and 32M.

Dice · Oct 28, 2009

Hi guys, what is the maximum dram voltage that people would be happy using 24/7? A lot of places are saying 1.65 is the absolute top, whereas others are saying it needs to be within a certain distance from your vtt. I saw that Fits had his at 1.71 earlier in the post. the reason is i have some to the ripjaw 1600 c7's running at 2000Mhz but failing memtest after a couple of hours. they are at 1.68v at the mo and im wondering how much more i can put through them without killing my cpu or if its worth dropping my multi and ocing my bclk a bit more, its @ 200 at the mo but seams to get a lot more arsey any higher.

Athlon2K15 · Oct 29, 2009

im curious to know why your able to select 21 as a multiplyer on the 750 when its only supposed to be 20. 133x20= 2.67Ghz can anyone else select 21 as there multi? or am i the only isoltaed incident?

keenan · Oct 29, 2009

It's a motherboard feature (Turbo mode) Some do 21 multi and others do upto 24..

Athlon2K15 · Oct 29, 2009

i dont think it turbo mode man,because i disabled speedstep and turbo mode but i can manually select a 21 multi

That seems unusual... I can only get the x21 multi on mine (can't select it) if I have turbo "enabled". So are you able to also get a x22 turbo multi when you select the x21 on your board?

gaximodo · Oct 29, 2009

it's maximum x21 with all 4 cores enabled (selected or turbo), and up to x24 with only 1 core enabled
