Time for a 2x4GB RAM kit, suggestions?

[Ket]

Title says it all really. I've been convincing myself I don't need 8GB RAM while my 4GB kit pumps out @ 2133MHz 1.65v, but one of the sticks has seemingly started to degrade (this is why IMO all memory should have a fan over them folks). I had to dial things back to 1866 7-9-7. Just the excuse I needed to go 8GB

After lots of looking around the best kit I can really see right now is the G.Skill F3-12800CL7D-8GBXH. Now, I'm not expecting a 8GB kit of memory to clock as well as 2133MHz, but 1866MHz with good timings is a absolute minimum. I'm open to other suggestions if people have any. The basic spec any 8GB kit needs to meet is;

- Able to do 1866MHz with good timings (lets say 8-8-8 or better)
- Memory kit needs to run cool
- Preferably be a low voltage kit capable of 1866 8-8-8

Have at it

ED - Few more details, I'm in the UK, so I need to be able to get the kit over here (many good kits don't find their way to the UK )

Shortlist:

G.Skill F3-12800CL7D-8GBXH 7-8-7 1600MHz 1.6v (£90)
Corsair CMZ8GX3M2A1866C9 9-9-9 1866MHz 1.5v (£65)

Those are the best kits I can find in the UK right now. I don't like Corsair but I'm leaning toward them for the low voltage.. assumption is with 1.6v the Corsair kit will be able to do 1866 8-8-8. If anybody can show some hard numbers for both of those kits though, I can easily be swayed back to G.Skill, I don't like how easy G.Skill kits die, but they love Asrock Z68 / P67 boards.

[Punisher!]

I would go for G.Skill but actually there is still no exiting 8GB kit.

[Ket]

I was afraid of a answer like that I'm really not looking for a kit that does 2000+ because with 8GB kits timings are pretty lax at those speeds making them pointless anyway, just something that can manage 1866 8-8-8 or better timings will fit the bill nicely.

[Ket]

Just found another kit that might fit the bill;

G.Skill F3-12800CL9D-8GBSR2 9-9-9 1600MHz 1.25v (£58)

Again though, very little is known about this kit it would seem no reviews for it....

Prices seem a bit heavy to me. These are just suggested as available in UK ...no hands on for me.

[Ket]

Ouch, those prices are heavy. I think I'd much rather hedge my bets with the Corsair 8GB 1866 kit and gamble on getting 8-9-8 timings @ 1.6v. For £65 it would be a great buy.

I'd stay from those super low-voltage kit if I were you. It can't go anywhere beyond 1800MHz at CL9-11-9-27 even at 1.65v on P55. (Base on this review(don't mind the language tho and here ))

Grab the G.Skill 12800CL7D-8GBXH or any kit with decent PCB and Hynix BFR H9C on them. You won't regret. (The F3-12800CL7D-8GBRH also has Hynix BFR.According to this)

And here's how to spot Hynix BFR chips.

There should be 4 solder pins under each side (left and right) of the chip.

[Ket]

I'll bare that in mind, thanks

[eXa]

Ive made a small list in THIS thread to track the Hynix IC.
Tho i wish it was bigger...

[Ket]

I think you can probably add Corsair Vengence 1866MHz kit to that list Would appear the kit probably uses higher binned Hynix H5TQ2G83BFR-H9C. I'll get pics when my kit arrives but the purchase has had to be delayed as the money I was going to use for th kit had to go on a new laptop battery and set of headphones at the last minute

If you are lucky, you may get 1866 8-9-8 with them, it will take some voltage though.

I can't believe you were expecting 1866 8-8-8 or better...shouldn't be expecting Elpida Hyper speeds or Corsair GTX3/Gskill 2200 CL7 from a 2x4GB kit IMO...

Telling people to put a fan over their ram has no merit either if it has a functioning heatspreader. My sticks keep under 40c in normal use while OC'ed and being pumped with 1.7v...

[Ket]

8-8-8 / 8-9-8 @ 1866 isn't unreasonable, I've seen 16GB kits do that with similar timings. Its pretty much a given the G.Skill kit will handle those timings, too. I've had 3 kits of memory die or degrade for absolutely no reason, each kit HAS had functional heatspreaders and not some POS for "bling". The one kit I do use a RAM cooler on is still working perfectly today. So what does that tell you about "merits"?

No.
Well, yes.
No.
No 2x4GB kit is going to do 8-8-8 at 1866, no 2x2GB kit other than kits with BBSE or Hyper will do it either. If you get really lucky and have a god-like PSC kit similar to Ripjaws 2200 CL7 you may get close to 1800 6-8-6, otherwise you'd have to lax to 6-9-6 or 7-9-7. (which isn't bad, especially on an intel Sandy Bridge setup like yours)

Show me an 8-16GB kit that does 8-8-8 at 1866, please. 8-9-8 is doable. By 2000, you are looking at 9-11-9 on almost EVERY 2x4GB kit...2200+ 10-11-10. I understand you don't want to run that high, but those Hynix chips dont do 1866 8-8-8.

By the way, ram coolers? They are for bling. Those little 40-50mm fans are practically useless. Who cares if you put a huge cooler on your ram that not only disrupts case airflow but in gskill's case has shiny lights on it to provide 20 CFM of air to your ram? A high airflow case setup should do that for you. Test bench, I understand. But on a test bench, I'd rather have a high-rpm san-ace on them to push them.
Also, MOST kits DO HAVE heatspreaders for bling, and its better to monitor temps before telling everyone to put a fan on them.
List of ram kits in my opinion that have heatspreaders primarily for bling, or heatspreaders that are nearly useless for dissapating heat, and will hardly benefit other than a negligible ~5c (unless your ram is on fire) with a lowly 20 CFM because they lack surface area:
GSkill Ripjaws, Ripjaws X and PQ
Corsair Vengeance and XMS3
All Crucial kits, except the high finned Ballistix that don't clock very well, nor is that design very efficient
All short Kingston HyperX
All ADATA Gamer and XPG kits, minus XPG + with heatpipe

Ironically these kits, in gskill's case are often sold with the fan for bling factor...a dominator kit with the high fins do actually benefit from the 25CFM cooler they bundle.

So what does that tell you about "merits"? :rolleyes

Quoting me like that and acting a troll will get you nowhere...

I'm not dumb.

[Lu(ky]

I understand this says 2x4gb = 8gb kits but I just picked up these G.SKILL Ripjaws X Series 16GB (4 x 4GB) 1866 F3-14900CL9Q-16GBXL only rated at a 1.5v from newegg for only $170.00 Also who says you have to leave more then 2 x sets inside for benches only..

I just bought the 2133mhz Mushkin Redline 8gig Kit from Aria PC for £105 they have the Hynix BFR chips. I'm hoping for around the 1800 mhz mark with tight timmings but will have to wait till next weekend to buy new board and 2600k.
I have read a couple of reviews about the mushkin Redline, Would be good if anyone who has first hand experience with them please chime in.

Why 1800 and not 2133?

[RAYTTK]

Why 1800 and not 2133?

I'm not sure what Im gonna get yet Sandybridge is new to me but in the past I have always had lower speed with tight timmings

[eXa]

Speed>timings for sandy bridge, and the kit is already 2133mhz so...

exactly

i tried 1950 cas6 lol n 2133 cas7 8 or 9 is faster

[RAYTTK]

Cool, You two have saved me wasting time with the mem LOL, Bought a MaximusIV Gene z today, 2600k should be here tomorrow. Booked a day off work come on Postman!

[Farmer Boe]

I've got my gskills down to 6-8-6-18 at 1988MHz and those things ripped it up in the benchmarks! So its not ALL about speed for sandybridge.

[eXa]

ofc not, havent claimed so either. Its just that sandy bridge like speed more than thight timings.

[Anusha]

Ket, i bought the 1600MHz model of the same 1866 you have listed in the first post. you might be lucky, but i was very unlucky as mine cannot do 1866 at same or looser timings nor 1600 at tighter timings at 1.65V. XMP is 1600 9/9/9/24/1T @1.5V. 1600MHz even with 8/9/8/27/2T wouldn't work with 1.65V.

weirdest thing is, they can do same XMP clocks with just 1.26V, i mean they were stable for 6 hours in memtest. that's nuf for me. i am so baffled why these cannot do better than stock clocks when they can run them at that speed with a massive undervolt.

u know i have a Z68 Extreme 4, but i don't think is has anything to do with this as you have your 4GB running at 2133.

my advise is, get something that will definitely do the speed that you want. that maybe is an expensive route, but less disappointments.

[PatRaceTin]

Hynix BFR is good for 4GB stick

[RAYTTK]

Not had to much time to play yet, I have Asus M4ZGene, 2600k@5ghz and Mushkins @2133mhz @1.65v with stock timmings the heatsinks are very cool to touch. Prime running now, 3DMark06 up nearly 8000 points more than my X58 with the same 480sli GPUs
