Massman Posted July 10, 2013 Author Posted July 10, 2013 (edited) Hahaha //edit: George, since I know I can trust your judgement, how much stretch is there on the MFR performance wise? Higher frequency is not going to help as you keep dragging the RTLs up too, but what about lower tCL and tWL? tRDRD should be possible at 4 with cold, I guess? Edited July 10, 2013 by Massman Quote
dumo Posted July 10, 2013 Posted July 10, 2013 (edited) It will scale up with cold Heres on air Edited July 10, 2013 by dumo 1 Quote
Hiwa Posted July 10, 2013 Posted July 10, 2013 Problem of performance is single sided, they can do some good timings at c8 and 9 with highvoltage and ln2. Quote
Alex@ro Posted July 10, 2013 Posted July 10, 2013 twcl huge performance hit is when tcwl is higher than tcl(CAS).when we speak about cas 11 tcwl 8is fine,pretty sure huge gains will not be seen also max benchable MHZ will go down.... Quote
hokiealumnus Posted July 10, 2013 Posted July 10, 2013 Looks like I just received another MFR kit. Heh, looks like they were recycling some stickers; this is a 2 x 4G kit. Hmm...I bet the gold would probably go well in a 1337 gank machine! :nana: Wait, no...Gank Machines (which astoundingly do exist) are red & black. This kit goes with the Gank Domination. Quote

Higher frequency is not going to help as you keep dragging the RTLs up too, but what about lower tCL and tWL? tRDRD should be possible at 4 with cold, I guess? I think tighter timings would help especially at lower frequencies, but as Dumo has stated tighter is not always faster. I could not get 3100 with those timings to pass, but the good thing about my kit is it seems to like voltage, 1.9 on air is fine so I am hoping they do well on cold. Hiwa is correct being single sided hurts the most, but I think if you could get 4 dimms (full bank) to run it would cancel out the single sided performance hit, but I am sure the IMC would have a tough time coping with full bank, decently high mhz and tight timings (can't believe I just said tight timings and MFR in the same sentence:p). Thinking about strapping the pot on these suckers but so much more PSC to bin atm. Quote
Crew Vivi Posted July 10, 2013 Crew Posted July 10, 2013 i would have enjoyed some high binned dual sided samsungs rather Quote
l0ud_sil3nc3 Posted July 10, 2013 Posted July 10, 2013 i would have enjoyed some high binned dual sided samsungs rather just for you girl 1 Quote
dumo Posted July 11, 2013 Posted July 11, 2013 (edited) @3000~3100 with optimized rtl helps Edited July 11, 2013 by dumo 1 Quote
Alex@ro Posted July 11, 2013 Posted July 11, 2013 i would have enjoyed some high binned dual sided samsungs rather here is you go vivi,i think with proper sticks and tweaking optimal temperature and a health load of voltage DDR3-3000 9-12-12 is doable.Performance should be somewhere in 2600 cas 6 psc land,not bad,miles ahead of this damn MFR's....

Crew Vivi Posted July 11, 2013 Crew Posted July 11, 2013 nono im saying they should have kept manufacturing samsungs and getting them to higher speeds, i got a nice pair of sammies at home too. but nice scores on air guys. anyone know what volts samsung die at? i mean im close to 2.05v on air and don't know when to stop Quote
Alex@ro Posted July 11, 2013 Posted July 11, 2013 should be juat enough on air,on cold i heard that 2.3 is good and they die fast at 2.6 1 Quote
Hiwa Posted July 11, 2013 Posted July 11, 2013 after 2v Sams stops scaling on air vivi, highest i ever boot air is 2900 C9 tight 2.05 and pass 8m, cold gave them more stability and max out close to 3ghz with nice sticks under cold -10 to -50 nothing change here with my sticks, i am more stable when normal air but i guess good temp for IC is about -10 tried them 2.2/3 Cold----Air 2.05 never killed one.

Same here i had 0 scaling with volts on air with 3770k, but on Z87X-OC i could get 2800 9-12-12 stable with more volts. But maybe that was just platform change that helped, i will try 2.1 today to see if it yields anything, Yea sucks that they dont scale with cold... that would have been heaven Quote
hokiealumnus Posted July 11, 2013 Posted July 11, 2013 Aren't you guys worried about your IMC at ~2V+ on air? I'm paranoid about that kind of thing. The max I've put through a Haswell IMC is 1.85V with the CPU on water. Can you degrade an IMC like that or am I being paranoid about nothing? Quote

Then learn from my mistakes lol Quote
TaPaKaH Posted July 11, 2013 Posted July 11, 2013 I ran a set of 2600C10 at 2.0V 24/7 from Aug2012 to Jan2013 with no damage at all. 1 Quote

Ran some Micron PFJ on ivy bridge with 2.2 for exteneded periods,hell i forgot the platform running and went in town,woke up next day to see it was still on.Ofc no damage.Haswell tinkering with 1.9-2V on air,no biggie,guess this IMC fear is because of Nehalem bad experiences,we are already 3 generations after that ...

hokiealumnus Posted July 12, 2013 Posted July 12, 2013 Huh; maybe I'm more paranoid than I need to be. Thanks for sharing your experiences guys. Quote
Hiwa Posted July 12, 2013 Posted July 12, 2013 Imc Degrade only with high vtt on haswell, 1.35 is enough on air for soft testing. Tried 2.0 million times on air but test only 32m Quote
