BSOD

[Lollipop]

So as some of you may or may not know i just build a new rig

The problem is with the memory ( i think)

As soon as the system was ready i OC'd it to 4.5ghz and set the bus speed to 105.1 and it worked fine, except every once in a while i would get a BSOD saying memory_something (Can't remember sorry)

So i turned down the bus to 100 and it didn't crash... until now, so is it faulty memory?

Did you try loosening the timings? out of interest what memory is it?, It could even be your mainboard chipset, No point changing the FSB just clock the multi up, From what i understand the 1155's don't like to be messed around with to much just multi and voltage.

Hi,

Bus speed tweaking, while possible, isn't really advised with SB. Some boards won't even tolerate a 2mhz increase in BCLK without becoming unstable.

Personally, at 4.6 on my 2500k I've left the BCLK unchanged at 100. Indeed, even when playing and going to 5.0 ghz once again I did not touch the BCLK.

Some use BLCK to get past an overclock wall, i.e. when mutliplier increase and vCore bumping etc. no longer give a stable OC, however that's far from guaranteed to work.

I've not played with BCLK myself but I guess changing it could well impact memory timings etc. too?

FYI: All I've changed on my system to get to a nice, stable 4.6ghz is i) Increase my vCore Offset to 0.050v and set my LLC from the default of "High" to "Very High". This gets me Prime and IBT stable with temps in the mid 60's. Note: I only needed to raise my LLC a notch to be stable at partial load, i.e. one or two cores loaded while others remain basically idle - typical of a gaming scenario where the game doesn't multi-thread well.

Cheers,

Scoob.

I manually set the timings in the BIOS to the specified

and i use some mushkin blackline

9-9-9-24

1600mshz

No one can help?

Leave the BCLK at 100. Are you at the correct timings and voltages for your memory to run at 1600? Some Blackline kits require 1.65v at 1600MHz IIRC. If everything is correct, try memtest out and see if it reports any errors.

memtest will have to wiat till i get my optical drive back

And yes i use 1.65 volts as it syas on the sticker

Try at 9-9-9-28 just to see if that solves the problem, If not then it's not a memory issue, I would run the Bclk at 100 though on the new i5/i7 CPU's i've seen alot of problems on some mainboards from people running over 100FSB, Those chipsets are just not good with frwq changes it messes up all the I/O's

Okay no BSOD's so far, i will bump this if i get one

In their download section they have a version that can run from a USB stick as well.

I do not have a USB available....

Pretty much SOL for using memtest then.
