Wait.

See what I did there?

They look like single sided ram sticks you have there (be Samsung HYK0). Bump your ram voltage to 1.8v (they wont do any better over that). Can verify that by the serial number on them (will have ****2500). Think 1500 is double sided, which you can add all the volts you like.

These are the timings I used on a 3930k for superpi 32m and are about as tight as you will get the sticks.

You might be able to get the speed up to 2480-2550 range using bclk, but most wont go much higher than that, some will do 2600CL10 though.

XTU really loves high bandwidth ram clocks, so the higher you can get them clocking, the better the score. Cache ratio as close to clock ratio too, you should get 45x at 1.2ish volts on cache.

1500/2500 doesnt indicate double / single sided, it indicates generation 1500 is hch9, 2500 hky0.

Dual and single sided G.Skill samsungs come with the 1500 and 2500 serial and I don't think his are Samsungs anyway because they are 8gb sticks which I'm unaware of them ever coming in

Good points, still, need to know the serial to get an idea.

Didn't notice they were 8gb sticks, just noticed the timings are exactly the same XMP as the 4gb sticks I had.

Just offering advice where everyone skimmed past for the dude.

Can't tell sorry. The heat spreader completely covers the sticks. I'll take one out and check it out after school pickup.

definitely samsung
if they're 8gb sticks they'll definitely be dual sided.
if they're 4gb, they will be either single or double sided samsung.
4gb dual sided samsung are the best of these.

I just did a bit of time looking at Samsung datasheets and 8gb is more than possible on single sided sticks in a 1gb X 8 config

HYK0 seems to come in two kinds. One has 256mb ics and 512mb. The other 512mb and 1gb

ok.
so basically, drop it to 9-12-12-21, and see how far you can push the frequency, while adding vdimm.
samsung loves high voltage, and most of us in the hwbot team use 2v+ regularly.
I'm not sure what dual sided sticks are capable of, but only way to find out is try.

The ss I showed above was based on the high density hyk0's, I know cause I pulled the spreader off one. The TRFC is the give away being so high. They went 9-10-12-21-1t. But different to the lower density double sided sticks.

Like Matt said, just have a go. If you can get to 2600 with some extra voltage, your on a good thing. The rest is extra timing and voltages. Try dropping the TRFC as low as you can, go 210, then 180, 141 and 108 and see if it passes.
