So I have this ASUS P8H61M-LE R2.0 motherboard. I just bought CMY16GX3M2A2400C11R which works and the BIOS has defaulted to 1333Mhz. Although the board is capable of (OC) 2200. I set the XMP profile option which is suppose to auto set everything which it does but I receive the message Overclocking has failed press F1 to adjust.
So I end up just leaving it on the default setting of 1333Mhz.
This is very frustrating because I jumped from an MSI p67a-c43, which handled any memory brand I threw at it plus the XMP setting handled then set the speed for what I wanted whether it was 1333Mhz, 1600Mhz or 1866Mhz. It would set XMP no problems.
This ASUS board has the XMP option but it doesn't work. I want to run 2200Mhz but I can't. There does seem to be the option of setting things manually-Primary, Secondary, Third Timings + Misc... I can't find proper instructions on how to do that.
Any help is greatly appreciated.
I'm 99% sure it's because of the CPU. H61 chipsets pretty much run at the max clock the CPU supports, and in your case thats 1333.
Although, if you have the option to adjust ram speed / clocks, try setting them manually. Look up the ram info in CPUZ. You only need the basics. Leave everything else to auto.
Example: 10-10-10-21 1T Leave all other options to default or auto.
Thanks.
So When I get something like a i5 3470 it should remove that ceiling and I can utilize 2400Mhz? For sure...
Btw is there another way I can look into the memory clock speed without using something like CPUZ, my previous experience with that was getting spyware knocked in my system real good.
No, the 3470 can go to 1600mhz dual channel (2 dimms populated) or 1333 with all four populated. That's stock rated speed. You can OC over that if the board supports it. Which it appears it does, but I'm not sure why it's not letting you. I would guess the timings are being set too tight with the auto setting.
Hmm. Well I can tell you that it will never run at 2400mhz. Sandy was limited to 2133mhz. You can go higher with more Bclk if you wanted to go that route. Are you setting the ram voltage as well?
Try this:
- Set ram speed to: 1600
- Set ram voltage to: 1.6v
- Set the timings to: 11-11-11-31 1T
- Set "'Row Refresh Cycle Time tRFC" to: 200
Leave everything else at auto. And see if that works. I went through a similar issue with my Z77 in my sig. I could not get all 4 dimms to run at anything higher than 1600. No matter the timings / votlage etc. One day just goofing around I found the answer. Tightening up the CAS timing let me run at 2133mhz, lol. Turns out anything higher than CAS 10 on this board (with all four dimms populated) = No boot.
Apply the XMP but manually lower the speed of the ram to 2000MHz, then set 1.15v VCCIO, that should be plenty enough to get you 2000MHz stable anyway, probably 2133MHz if you're lucky.
I entered 200 under tRFC and rechecked it twice over and a no go.
The voltage number 1.15 under VCCSA and no luck. The only thing I have to work with immediately is Manual option giving BCLK/PEG 80 to 300 and as far as I could go on that was 104 3224ghz an 1399Mhz. My CPU can go to 3.4 even though its an i5 2400.

no luck choosing 1866 and setting your voltage recommendations. I tried doodling around with ASUS OC Tuner and it shifted my supposed locked cpu to 3.5 ghz. and then tunning my ram to 1372mhz. weird.

that fact that your ram is at that speed means you're playing with the BCLK, please trust me when I say you don't really want to be doing that, causes more problems than it's worth
uh huh, well thx for your help. I'll looking into another board in the near future. An hopefully the manufacturer sticks to what it says on the box.
