Flares on Bulldozer

[Zeus]

After searching high and low for a 2000 C7 Flare kit i eventually gave up and bought the lower grade 14400 (DDR1800) C9 kit. This kit is rated 9-9-9-24 1.65V

The first thing that hit me was how beautifull these rams are and how well they suit the Crosshair V Formula:



Sorry for the very bad image quality but the light was very low today.

As an added bonus, this kit has black pcb's, yummie.

So, i went on to test them and i was qiute surprised i have to say. The thing is, it doesn't like tight Trcd and it doesn't like Tras <26, any other timing can be pretty tight i found.

I haven't spend much time with the rams but so far i got them running 7-10-7-26 Trfc 90ns rock stable with 1.65V (haven't tried volts more yet)

First tested 15 loops of test 5 memtest86:



Don't mind the timings and speeds, it's an old version of memtest but it works fine.

Booted into Windows after that and ran memtest in Windows, 500%:



Then i raised ref clock some to see if i could match Dave's bandwidth in Aida:



I think i did, or at least close enough (i don't recall the exact numbers). As you can see, it ran DDR2060, still with 1.65V

I'm pretty sure the kit can do more as long as i keep Trcd at 10 but so far i'm quite impressed. I know there are better rams out there but none that will suit the mobo like this.

To be continued.

How much did you pay for that kit?
~€50-60?
My 1600 C6 Ripjaws do that well, priced at $55 USD when I bought them.
Pi kit is much better, still not near the 7-9-7 Flares though.

You need a kit that will do 7-9-7/7-10-7 at 2200+ or 8-10-8 past 2300 to beat Hyper on this platform it seems, considering good Hyper should be able to near 2100 stable 7-7-6 and who knows what at 8-8-7. Considering Infrared was able to run Cinebench at 2300, I'd guess 2200 at least would be feasible. (Corsair 1600C6, 2000C7, GTX2, STT 2000 C7)

My Hypers are consistently beating my PSC into the ground on Thuban for 24/7. 1890 7-7-6 @ 1.55v just beats the crap out of 2040 6-10-6 @ 1.67v in AIDA with same NB speeds. (Read is about same (slight edge toward PSC), write/copy down ~500-600 MB/s for PSC) 6-9-6 makes no change in AIDA other than ~30 MB/s and I'm not stable at all with it. Hopefully that is just a product of this motherboard, however it is disappointing. I hope to test more thoroughly with FX when it get it

I'm glad you like how the kit looks though.

I have one good kit (Trident 2000 9-9-9-27) that does 2260 7-9-7-22 1T with 1.7V on SB. Going to test them on FX as well, but I think it will be similar or even better.
Couldn't lower to 6-9-6, so I think it's not PSC, but very good BBSE. Am I right?

Flares are definitely looking good, but I never found 2000 C7 kit. Nice purchase, Eugene .

Yeah, BBSE. I wanted to pick up one of those kits too, they are guaranteed BBSE and seemed to OC well. There was a few kits on MemoryC a few months ago, now removed I bet they will do pretty close to 2100 7-8-7 if they do that at 7-9-7.

My Pi requires tRCD +4 CL for best clocks, it's kind of rediculous. Peak CL8 would be 8-12-8 ><' I've benched 32M at 6-9-6 at 2055 6-9-6 on Thuban but I can't even web browse at those speeds regardless of voltage. 2000 6-9-6 just reboots instantly in Prime.

Flares were binned to tRCD +2 I think, for the AMD platform due to its sensitivity to tRCD. chew* posted 32M at or near 2200 7-9-7-15 with Flares at 1.7v or less several times I believe. I just don't understand, since most other PSC likes tRCD +3 and tRAS usually looser than Hyper.

I can't really say what's better but i know that 2000 7-7-7 on my old C4F with my Hypers seemed stable but the system froze multiple times per evening in windows. Reverting back to ~1700 6-6-6 solved this. Don't know why though. Maybe Hyper isn't that good at higher speeds/relaxed timings.

This is my first time with PSC so i'm not familiair with it, just trying to see what i can do with it. It's quite obvious TRCD is PSC's weak point and i think binning is mostly done by TRCD. Unfortunately this kit wasn't as cheap as you said Beep, it was about €83,- or something. Maybe i'd spend to much on it and could have gotter better but i just wanted to try the Flares. If it was utter cr@p i'd had a destination for it but i think i will keep them.

Right now i'm memtesting them at DDR2100 7-10-7 altough that required a slight bump in voltage. (225% errorfree yet)

I will do more testing and comparing with Hyper but it seems speed is far more important than timings on FX cpu's.

If only i could find a 2000 C7 kit...

Definetly a nice looking kit Eugene and looks like their clocking pretty well too!

Not sure if this will help you, but it may give you a starting point...

These were my stable clocks with the Mushkins @ 1.65v (more v's didn't offer much):

1930 @ 6-9-6-24
2040 @ 7-10-7-24
1970 @ 6-10-6-24
2080 @ 8-10-8-24
2120 @ 8-11-8-24

I'm sure your better with mem then I am.
FWIW, the 2040 7-10-7 gives best overall performance.

For some reason I feel like your board (or something O_o) is holding your mem back. 2200-2400 stable should be doable CL8 according to guys like the stilt and other higher profile overclockers, even Leeghoofd said 2400 was easy.

I just think so because of your lack of stability with the Hypers, seems like my Pi kit is only ~50-60 Mhz better than yours at given CL, but I can do 32M on Thuban up to 2150. 32M is no means of stability, but usually when ram related doesn't gain much more than a few ten Mhz over stable speeds

Thanks Dave, that will give me a nice guideline.

Just did DDR2100 7-10-7 HCI memtest stable with 1.68V:



Not bad for a 1800 C9 kit imho.

[FlanK3r]

nice Zeus! At FX looks better than at Thuban. But at my FX station I have now RipjawsX 2200 MHz 8-9-7. This FLares stay still at Thuban system. At Thuban I can reach more than 1900 MHZ 8-9-8

Very Nice Zeus!
My kit won't come close to that (it's pretty old though ~2-3 years), so that list may not be very useful...

Slightly OT, but it seemed like a good place to post this.

Does anyone have any info on this kit: (Patriot Viper X / 2000 9-11-9)
http://www.newegg.com/Product/Produc...82E16820220535

I haven't really seen any info on them but the timings look PSCesk and the price is good!
8gb Kit for $70 (after rebate).
