M5A99FX PRO R2.0 & Patriot Venom Red 8GB DDR3 PC3-19200C10 2400MHz

Seanie2 · Sep 25, 2016

Hi I was bored and happened to run PassMark Performance Test on my system and was shocked to see that my memory was scoring an apparently quite low with a Memory Mark of just 1,287 which is dragging down my whole PassMark score.

I'm wondering if perhaps the memory is set up wrong in the BIOS. It's 2x4GB sticks of Patriot Venom Red DDR3 PC3-19200C10 2400MHz.

Does anybody out there have experience of this mobo/ram setup and know what the correct BIOS settings are for this memory?

Get the free app CPU-Z and check the memory tab to see what the DRAM is actually running at. Also let us know what CPU

Hi the CPU is an FX-8350. CPU-Z reports
Dual Channel DDR3 8GB
NB Frequency 2207.4Mhz
DRAM Frequency 1070.2Mhz
FSB: DRAM 3:16
CL 9.0 clocks
tRCD 11 clocks
tRP 11 clocks
tRAS 28 clocks
tRC 45 clocks

1.65V
• PC3-19200 (2400MHz)
• 10-12-12-30

Wrong memory for an AMD FX CPU. When overclocked, 2133MHz is about tops.

At non-OC speeds FX CPUs support 1866MHz with one DIMM per channel and 1600MHz with two DIMMs per channel.

Your at about 2133 (2140) with a tight Cl, try at 2400 with stock timings and will prob be fine (or slip it back to CL11), if no joy raise the CPU/NB voltage to 1.25 initially

If your overclocked I would try running at:
9-11-11-28
DDR3-2133MHz
Dram voltage 1.60v - 1.65v

That's what he said he was at....(well 2140), 2400 may well be within range

Hi. So before I got your reply I thought it might be an idea to update the BIOS as there were several new revisions since the board was shipped. Update went fine but then I noticed that the system wasn't set in "performance" mode and so I changed it to that which apparently knocked out my previous settings. If I recall the system was overclocked automatically with an Asus utility that came with the board, my own experience with overclocking manually involved scribbling on pins with a pencil in the 90's. I'm saying that just so that you know I don't really have much idea what I'm doing here!

Anyway, since updating the BIOS and switching on performance mode CPU-Z looks like this;

It's dropped the memory score in PassMark by a few points but it seems negligible. Perhaps as Calvin says I've got the wrong memory for an AMD FX CPU?

Here's a screenshot of my BIOS,

The best I could set the memory frequency at manually was 1728Mhz, anything higher and the system didn't POST. I don't know whether I should perhaps run the auto-overclock utility again or if somebody might know which of those settings need tweaking?

ANy OCing should be done manually, would try the CPU to 4.4 or so and then try with the DRAM - 2400 may well be to much for the CPU. I run 2400 on my 8370 rig and did an article on 2400 sets:

http://www.tomshardware.com/reviews/dram-benchmark-fluctuations,4080.html

but haven't found a lot of AMD CPUs that could effectively run 2400, sounds like yours 'should', but maybe not

Hi thanks for the advice, I read your article and a few others and decided to have a go at manually overclocking. Managed to get the CPU up to 4500Mhz and its nice and stable but I had no real luck improving the memory score much in PassMark. However I did download other baseline scores for this CPU/Mobo combo and it seems that my memory mark score isn't too shabby in comparison with these. Thanks again for your help.
