1366 X58 Xeon 5650

Not sure if its heat or a poor clock, but my 5670 gets to about 79/81 deg and the machine hangs.. From what i read thats abuot the thermal limit. Would the heat cause it to freeze or is it more likely to be a bad clock?

The thermal limit is near 100c so i doubt it's that. I can't help though as I've yet to get my chip yet.

mines bottling out at 3.4 . got my ram low (1333) to rule that out . not sure about uncore ratios . voltage is 1.28 which I think is high enough .

You really need to know your stuff to overclock on a Foxconn.

I doubt their forums are still active now, but they used to have a Quantum force board that had some really helpful members on it.

first we need to identify the problem, so we need to isolate the BCLK
set Multiplier to 12x leave the Core Voltage as it is for now (btw 1.28v is not high, 1.4v is the max safe, assuming your cooling is sufficient)
set the UNCORE the lowest possible value, in order to lower the UNCORE even lower you will need to lower your RAM.
As you increase the BCLK increase the vtt Voltage(your mobo may have a different name for that) ,a lot of people say the max safe voltage for vtt is 1.35v (personally I have vtt 1.368v for my x5650, because I think 1.35v is very conservative)
set the lowest QPI.


now test the following and report back

BCLK 180, core clock 21060Mhz (180x12), FSB : DRAM ratio 2:6, Ram at 540Mhz(1080Mhz), UNCORE 2160MHz, vtt at least 1.25v(maybe higher)

run Prime95 Blend test for 20 min, if not stable increase vtt(or IOH if you have to), if stable continuous increasing the BCLK.

BCLK 190, core clock 2280Mhz (190x12), FSB : DRAM ratio 2:6, Ram at 570Mhz(1140Mhz), UNCORE 2160MHz, increase vtt

run Prime95 Blend test for 20 min, if not stable increase vtt(or IOH if you have to), if stable continue increasing the BCLK.

BCLK 200, core clock 2400Mhz (200x12), FSB : DRAM ratio 2:6, Ram at 600Mhz(1200Mhz), UNCORE 2400MHz, increase vtt

run Prime95 Blend test for 20 min, if not stable increase vtt(or IOH if you have to)

You reach BCLK 200Mhz, time to set the ram to 1600Mhz

BCLK 200, core clock 2400Mhz (200x12), FSB : DRAM ratio 2:8, Ram at 800Mhz(1600Mhz), UNCORE 3200MHz, increase vtt a lot (because now you jump from UNCORE 2400MHz to 3200MHz)

run Prime95 Blend test for 20 min, if not stable increase vtt

You reach BCLK 200Mhz with ram 1600Mhz.

Now you ONLY have to increase the Multiplier and the vCore.

BCLK 200, core clock 4000Mhz (200x20), FSB : DRAM ratio 2:8, Ram at 800Mhz(1600Mhz), UNCORE 3200MHz, increase your vCore.

run Prime95 Small FFTs test

Stumbled upon this and had to post.

Read the entire thread and it convinced me to buy a x5670 to replace my tired 920. Hoping the higher multi will help as my board can be a bit flaky with bclk 200+
 
right kylew

got it up to 18x190 3.6 and got a cinebench r15.0 score of 839 . its been crashing o lot so ive been increasing the voltage until it doesn't crash lol gonna play a game now to see if it doesn't catch fire lmao
when I did the cinebench run coretemp went up to 63 on the highest core so should be ok
cheers
edit just put the ram up to 1536 and got a cinebench score of 848 . not bad for a £69 chip going to push for more after the weekend when im off for a few days

kylew you are a great help and thanks alxandy too

... And ECC ram they can be overclocked too. Just look for Hynix ECC 8gb/stick ram, they are really cheap, only around 10-12 pounds/4GB.

Has anyone switched out their ram for ECC? They do look pretty sexy.

Hello, new to the forum.

Love these (cheap) Xeon's, running 4.4Ghz 24/7 now. With temps up to 81.
To be honest, I haven't tried to push it further since the temp is a bit high. My 360 rad is a bit thin, thinking replacing it with a thicker one 45mm+ maybe?

Love this forum btw, regards from Norway :)

You need to put the memory setting to maximum rather than standard.

Running it on standard is no indication your CPU is stable at all.

Try again!

Just a quick question please, how much slower would these be 4.4Ghz compared to the new 5930k at same clock of 4.4Ghz?

Trying to decide whether i upgrade or just buy one of these Xeons.
