Explain these numbers please

[Nicolasb]

Hi guys,

 

i just ran a 3dMark test and came out great (above the score of high end gaming pc's) but after reading the specs of my pc I came across this

 

Memory 16,384 MB Module 1 8,192 MB Corsair DDR3 @ 667 MHz Module 2 8,192 MB Corsair DDR3 @ 667 MHz  

@667 mHz?

This seems a strange number (low)  

Can anybody explain this?  

2nd question now that you are here:  

I get random frame drops in-game and cant seem to pinpoint where they are coming from  

I'm running with these specs:  

graphics Card NVIDIA GeForce GTX 970 Vendor Giga-Byte Technology Co., Ltd. # of cards 1 SLI / CrossFire Off Memory 4,096 MB Core clock 1,178 MHz Memory bus clock 1,753 MHz Driver name NVIDIA GeForce GTX 970 Driver version 9.18.13.4709

Processor Processor Intel Core i7-3770K Processor Reported stock core clock 3,500 MHz Maximum turbo core clock 4,691 MHz Physical / logical processors 1 / 8 # of cores 4 Package LGA 1155 Manufacturing process 22 nm TDP 77 W

 

General Operating system 64-bit Windows 8.1 (6.3.9600)

Motherboard ASUSTeK COMPUTER INC. P8Z77-V LE PLUS Memory

16,384 MB Module 1 8,192 MB Corsair DDR3 @ 667 MHz Module 2 8,192 MB Corsair DDR3 @ 667 MHz

Hard drive model 128 GB Samsung SSD 840 PRO Series  

 

Thanks for reading and helping out!

1. That's normal, it is still 1333MHz

2. Which games?

[harrynowl]

667MHz = DDR3 1333MHz

For the FPS issue, check all your drivers, it could just be a badly made game or you are pushing too much out of it (turn down the graphics a bit).

 

As for 3DMark, It means you have 16384mb of ram (16GB of ram) and that Module 1 of ram is 8192mb Corsair DDR3 along with Module 2. So you have 16GB of DDR3 ram in total, with 2x 8GB Corsair DDR3 installed. The Memory clock at 667Mhz seems quite low but that is correct, it's DDR3 1333Mhz. But in these synthetic benchmarks ram is hardly used as much as say your GPU / CPU.

The weird ram speeds is because DDR memory is Double Data Rate, which means that you can pretty much double these speeds, so you'll end up with 1333MHz.

I can't explain the frame drops though. In what games do you get frame drops? If it is AC Unity, it is just because the games was pretty much released before it was optimized.

The speed of the ram is double so 1333Mhz, the weird sizes is because of the Decimal and Binary and apparently the fucking shitty standard that the fucking manufactures follow.

I get drops in Farcry 4 on ultra settings, these appear to be random drops in frames (from arround 90 to about 70 in a blink) but they seems to make a stutter rather than go smoothly (I have the nvidia ingame fps counter as reference)

 

Could it be that there are 2 drivers working against eachother? ( I just switched out my gtx680 for the 970)

 

It seems like I'm overreacting about the drops, but they do bother me a bit.
