Updated BIOS but which XMP profile do I use?

[elrasho]

Over the holidays I decided to update the BIOS on my mobo.

It was on something like 0822 and is now on 2204. I noticed in CPU-Z my core clock has gone from 4700 to 4900 (sometimes touches 5000 too) which is a nice surprise.

Do I now need to select an XMP profle for my RAM to boost their speeds too? In the BIOS XMP is disabled, when I enable it I have a choise of Auto, XMP1 and XMP2

Thanks

Select XMP1 and see if it boots ok and check timings after.

Thanks, what do you mean by timings? Also what is the different between XMP1 and XMP2 I did some google searches and there's loads of contradicting info

 

[elrasho]

timings
dram frequency
cas
ras to cas
cycle time
command rate
those are some of the major timings theres also more if you delve really deep
but most people dont need to
look in cpuz memory tab/section
dram frequency is your current speed
multiply that by 2 as its probably ddr ram unless its ancient
if you havent set a xmp then its probably lower than it can be

then in cpuz
look in the spd tab/section
the one furthest to left is probably your current speed with no xmp
the others show what speeds its capable of
the xmp profiles should be listed there

Thanks I will have a look tonight

OK this is what I got:

top pic is when XMP was disabled in BIOS
bottom was when it was enabled in BIOS and set to XMP1






Both are identical ???

 

[elrasho]

It's a little confusing
As there's a memory tab
And an spd tab
The spd tab shows the possible configurations your ram
Is capable of not it's current speed
So yes both will be identical
If you disable xmp then look at memory tab NOT spd tab
It should say 1066 (x2)
Then enable xmp and look in memory tab
It should then say 1600 (×2)

OK this is with XMP1 enabled and me running a game in the background



That looks OK right? as in I'm running at the correct speed for my RAM?

 

[elrasho]

Yep that's 3200mhz (2×1600 as it's double data rate ram)
And cas 16
Going by the part number in your previous spd screenshot
That looks correct

Awesome thanks

What goes the XMP2 profile do?

Got ya thanks, I'm happy with where I'm at. After updated the BIOS I got another 1700 points on 3D Mark

My CPU used to max put at 4700 now it goes upto 4900 most times
