Yeah thought so. It's a bit weird comparison. Although I still like to think that I didn't fully understand what he was comparing. Large size vs small size RAM or fast MHz vs slower MHz RAM.

Was the 10fps jump for min, avg, or max fps?

And no matter what, I'm going to change the config of my new box to 2 x 16GB DDR4 sticks with the highest MHz. With tighter timings playing second fiddle now.

I ran some benchmarks with the F2P shooter, APB Reloaded. This game is CPU intensive and requires high single thread performance, perfect for this test.

Since this game is open world and mutliplayer only, it's impossible to have the same exact load for each test. Basically, I stuck to the same district/map, with over 80 players (100 max). I drove the default starting vehicle around the center of the map where most of the action is, and ran 5 benchmarks for each RAM setting. Frame times were recorded using Fraps. I waited at least 20 minutes while in game before running the benchmark to make sure all the player assets loaded in.

I tried to keep the CPU core close to 4.6GHz, and the uncore to 3.4Ghz. I used 3 RAM speeds, SPD default, X.M.P, and overclocked. Not as detailed as other tests here, just wanted to see if my RAM OC made any difference in performance in this game.

System Specs:

CPU: Intel Xeon X5690 @ 4.6Ghz
Motherboard: Evga X58 SLI Rev A1
RAM: Crucial BLT2C8G3D1608ET3LX0 (3x8GB) triple channel
GPU: Nvidia GTX 970

In game graphics slider set to max with a few things set to false:
Warning: Spoiler! (Click to show)
UseVsync=False
SmoothFrameRate=False
VideoQuality=5
Bloom=True
HighQualityBloom=True
bAllowStaticDecals=True
bAllowBlobShadows=True
bTrilinearFiltering=True
AmbientOcclusion=False
Distortion=False
AnisotropyAmount=16
Fullscreen=2
MaxSmoothedFrameRate=62
MSAA_Amount=1
ResX=1680
ResY=1050

Test 1.) 2000Mhz 9-9-9-24 1T (Overclocked):

Min: 98.4 (95, 103, 103, 94, 97)
Max: 122
Avg: 118.813

Test 2.) 1600Mhz 8-8-8-24 1T (X.M.P.):

Min: 95.2 (93, 88, 99, 97, 99)
Max: 122
Avg: 118.363

Test 3.) 1364Mhz 9-9-9-24 1T (SPD, auto):

Min: 86.6 (71, 94, 97, 93, 78)
Max: 122
Avg: 115.378

Full benchmark results for those interested:

In my case the max and average both boosted. As far as I could tell. I dont think it impacted minimum negatively, because perception of frame dips decreased altogether

I am a complete noob with it comes to memory overclocking. I watched this video on if i should upgrade my 2500k that shows memory speed can make a difference (this wasnt the case when i built my rig in 2011):
https://www.youtube.com/watch?v=frNjT5R5XI4

I have a very good kit of ddr3 here:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231445

I would like to try and get 2133 out of this ram do you think its possible? What would be the timings and voltage i would need to enter into my bios, remember ive literally never OC'd ram lol.

Thanks.

RAM oc is not easy. You have to look up some guides. You can start with just setting to your desired speed and leaving all on auto and see what happens. If nothing good (most likely) set voltage manually. If that brings no improvements you have to start reading smile.gif really.

Cheers

probably but keep in mind 2133 11-11-11 is about equal in speed to 1600 8-8-8
for a start aim for 1866c9 or faster still 1600c7

some ram chips may respond well to extra v some may not ~1.6v should be fine maybe higher if its responding
run memtest86+ usb boot after each adjustment you make to the ram up to test 8
once you have found what you believe to be stable run it for about three passes to make sure followed by further cpu tests in windows

use maxxmem2 to compare the performance of different settings so you know what you have changed is actually faster as sometimes what you think is faster will be slower

Memtest86+ is ****e, always was. I recommend GSAT (Goole Stress App Test) instead, brings unstable memory much faster to its knees and does not validate unstable OC as memtest does on regular basis.

Cannot tell you how many times I ended with unstable mem OC because of it... (while 48h+ stable in memtest...)

This software is so old ! i don't think it works very well with modern Dimms.

Also starting at 3000MHz with the lowest CAS seems to be the best for gaming.

Edit: sorry for the double post and auto quote, my mistake, it's hot today !tongue.gif

After doing more research im gonna keep my ram stock lol. I had no idea how much latency affected performance, im happy with 1600 cas8. Thanks for replies.
