Flashing BIOS, Memory timing problem

post #1 of 5
Thread Starter 
OK, I tried to label the thread as detailed as I could get.

First thing I did was I flashed my bios for my motherboard. Basically I was running a updated version of the bios that supposedly didn't "support" my i5-2500k....so I had to revert back to an 'older' version of the bios that supported the i5-2500k, if you look closely on the MSI website for my board 7673v17 is the bios that supports the i5-2500k, that came out on 1-7-2011, and the newest bios supposedly doesn't support the i5-2500k or at least doesn't explicitly state that it does and the newest bios is from 11/9/2011...? doh.gif

So here's what I've got:
http://us.msi.com/product/mb/P67A-C43--B3-.html#/?div=CPUSupport

with my rig details below.

Now the details on my memory state that memory timing should be 9-9-9-24 T1
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211409

Before I flashed my bios I was running 8-8-8-26 T2

So I flash my bios, reset all my overclock settings, which the new bios has helped my overclocking somewhat, and then when I go into changing my memory timings back to what it was, save and exit, the pc won't boot, and I either have to cold start or reset the CMOS.... madsmiley.png

So I'm wondering whats up... I think I'm going to go slow and figure out which timing is off.


Before Memory Timing: 1600 - 8-8-8-26 T2
After Memory Timing: 1600 - 9-9-9-24 T1

Questions thinking.gif
From my understanding, lower timing numbers = faster?

Should I really even bother trying to get the numbers down to 8 from 9?

Is it the command rate? From changing it from T1 to T2?

I just read that it could be XMP (Extreme Memory Profile) in bios? I've got that enabled, always have....

I won't be able to get to my rig till this afternoon so hopefully I have some possible solutions to my problem.
Basically when I change my memory timings the PC will restart and quickly turn back of, do that a few times, turn on, no monitor on, I'll manually power off, then reboot and the bios start comes back. thumbsdownsmileyanim.gif

Alright, little update on this...

Cannot change any timings or else the PC won't boot...won't even post...

I was reading up on memory voltages and I heard that 1.65V is bad? My bios showed that my memory on auto voltage was operating @ 1.6485V. I lowered that to a manual setting of 1.608V which in bios shows switching from 1.598 to 1.600V. @ 800MHz or 1600 speed.

So basically my other question is regarding voltage. Is it ok to run a low voltage @ 1600? It says 1.65V @ 1600 on the memory but I'm running 1600 @ 1.6V and it seems fine sofar... Should I just call it good? or set it back to auto and 1.65V?

as long as it's stable it really doesn't matter how low you go with voltage smile.gif

in regards to your first question... command rate and cas latency are probably the two biggest factor for bandwidth and performance of memory, so it will be hard to say which one would be better (8-8-8 2T or 9-9-9 1T @ 1600mhz) I am inclined to say that cas 9 1T would be better.

If you got the adata xpg gamer series.. those should be able to overclock some.. change the timing to 9-11-9 1T and you should be able to do 2133 with 1.6-1.65v thumb.gif (or 9-11-10 1 T)

The new bios supports the 2500k. They wouldnt remove spport for that. The reason they dont say it is supported is because it is implied from older versions.

When I flashed the newest version of the bios the Intel Turbo boost wasn't present as an option in the bios... I don't know what happened but it wasn't there...This 1.7 version has turbo boost... I think if all is well I'm not going to mess with flashing it again...

The bios is very limited anyway. Kinda sucks, no PLL voltage control or anything...just the real basic stuff. It's nice that I get 4.4GHz though on my i5-2500k with very little voltage bump.

It's stable in my book. Ran prime95 for 4 hours with no errors or warnings. I've got memtest which I could run as well. Might go for that too.
