Low CPU benchmark? (i7-8700k)

[elert]

Hi

 

Just (re)-installed my i7-8700k. I received my new cpu aswell as my asrock z370 extreme4 mobo last week but ended up having to rma the mobo because the pc wouldnt turn off when i shut down the pc. 

Now I have received a new mobo and i no longer have the problem.

 

I have now done a little benchmarking. I've used Passmark primarily and some cinebench but I believe my scores are very low for some reason - at least they are lower than what they were last week with the other mobo! The reason im writing this is because last week i got a 14.816 score with stock settings on Passmark as opposed to the 11.993 that I get now, also stock ! Ive taken some screenshots, hope you can see it. The one thing that is differnt now is that my PC wont boot with my 2x8GB of 3000mhz ram installed in dual channel - so right now they are running in single channel - is this why?

 

edit: did a cinebench at 4,8ghz and scored 1324. Last week i got a score of 1431 with the exact same settings. With this overclock I got a Passmark score of 12.598 and last week i got 17.072 with these settings!

My first thought is that your RAM running in single-channel is the culprit.  You should probably get that sorted out.

Im thinking the same. Im just not quite sure what to do. PC wont boot when inserting ram in slot 1&2 (A1&A2) but will in 3&4 (B1&B2). Tested each stick and they both work fine individually. And it works when plugging in both in B1 and B2 at the same time but then its obviously only single channel. And this is the replacement mobo i got after returning the first one i got last week

What does your mobo manual say to do?  Isn't it usually A2 and B2?

Yes thats what the manual suggests. But it wont post. Only if i put a stick in B1 and/or B2

It isn't a suggestion -- it's the proper installation procedure.  I hate to say it, but if that isn't working your new mobo will need to be RAM'd also.

Yeah, I'm sorry that's happening to you.  I definitely feel for your pain.

Loosen up your cpu cooler or just reseat the cpu cooler had the exact issue with the dual channel ram just a different motherboard though (MSI z370 gaming plus)

Thanks for your suggestion! Unfortunately, I already tried this. I even took out the CPU itself and when reseating the cooler i was very careful to tighten the 4 screws holding the cooler equally to get as good a connection as possible
