FEATURED Team Group Xtreem 8GB DDR3-2666 C11

[Woomack]

Some days ago I found nice deal for Team Group Xtreem 2666 C11 kit and I just couldn't resist. It cost me ~$110 with shipping so maybe not cheap but considering that in Poland all cost ~20-30% more than in US and it's 2666 kit then I think it's good price

I started to test it with i7 3770K on stock cooler ( yep, I know it sounds like broken ). Later I will add some more results with cpu on ss cooling but I think it doesn't look so bad for now.

Team Xtreem 2x4GB DDR3-2666 is based on Hynix MFR PBC. Kit includes 2 single side sticks.
This Hynix IC is designed to work with voltage up to 1.975V and temperature from 0-85*C. Recommended voltage is 1.5V +/-0.75V but maximum is +0.4V what gives us 1.975V.

Tests 2400/2600/2800

I will skip 2666 for now. You just have to trust me that this memory is working on stock / XMP settings

2400 10-11-11-31 1N 1.65V



2600 10-12-12-31 1N 1.735V



2800 11-13-13-34 1N 1.75V




I couldn't make it work @2666 at tighter timings than 11-13-13 but I was able to lower voltage to 1.57V at stock 2666 11-13-13-35 timings with CR 1N.

Max clock ( for now ) and max stable settings

Max clock using already mentioned Intel stock cooler for cpu is 2850 11-13-13-35 1.775V what is my cpu's IMC limit on air.

Max stable clock ( probably also because of IMC limit ) is 2800 11-13-13-35 1N 1.75V




That's all for now. I will try to update this thread with some more results when I find more time for tests.

One more screenshot. 2800 10-13-13-31 1N , tight sub timings. Benchable but far from stable.




Edit:
XMP/SPD AIDA/MemTweakIt screenshots added to 1st post

Thanks for sharing.

 

[Woomack]

Max clock for now 1540 11-14-14-37 ... valid from CL12 , seems like my CPU won't make more. Time to switch to AMD or wait for haswell that looks promising.

Nice find Woomack!
I think $110 for that kit is definitely on the cheap side...wonder if it'll be cheaper in the US?

 

[Vsalvis]

Looks like newegg has them in stock for $120 -- http://www.newegg.com/Product/Product.aspx?Item=N82E16820313322

Single-sided Hynix MFR based stuff is starting to pop up all over the place.

Do you by chance have a comparable CFR based kit? It would be interesting to compare results from a double-sided CFR kit at same CPU speed and memory timings to your results with these single-sided sticks.

 

[Woomack]

The only difference is in tRFC. My CFR can run @2600-2800 set to ~170 tRFC while for MFR I had to set it to 250+.
In SPD there is 467 what is higher than manual max for MSI MPower but from auto it's setting exactly what it should be. On both my boards so MVG and MPower this memory is overclocking the same and is fully stable @2800 11-13-13-31 1N.

CFR results are for example in my Geil EVO Veloce 2133 review. CFR@2800 11-14-13-36 1N, tRFC 174 while Team Xtreem/MFR @2800 11-13-13 needs tRFC 256+.

I don't think I will find any results on the same cpu speed and all other timings ( except tRFC ) but from what I remember, results were +/- the same.

Here is review of Team Xtreem 8GB 2666 C11 if you wish to read it.

I've also checked it on ASUS CHVF with AMD FX8120 and FX8320. Because of some platform limitations I was able to run it up to ~2600 ( higher boot but wasn't stable ).

Hynix MFR is looking quite good lately...like that new 3000mhz Vengeance kit (1.65v dayum)

 

[Woomack]

little update on haswell:
DDR3-3000 12-14-14-37 1.75V ( have to check lower voltage )

 

[Woomack]

next little update:
max clock so far 1816.2MHz / DDR3-3632

[ivanlabrie]

That's bananas
GREAT run man!

 

[keny]

May look into snagging some of these as I don't have any real high speed ram (2600+)

 

[Woomack]

It's probably the cheapest 2666 MFR kit on the market and inside is about the same as most other brands offer in DDR3-2933/3000 kits.

 

[ivanlabrie]

Gonna have to save for one...I'd like to try a 4x4 config with these for kinks.
Impressive results

wow that is awesome Bart, nice OC!

Finally got chance to mess with a set of these and I can't get 3000 out of them on haswell !!! Don't know if there is some magic setting that needs adjusting, but it will make 2933 @ 1.65v no problem (just set the speed and go) but anything higher than that returns a boot fail @Post, I'm a total noob on haswell and I literally just installed a os and played with the ram, so not up to speed on the oc settings as they seem slightly different to ivy, but surely the imc should be able to handle 3000 at stock anyway.
