Tried 4.1GHz because it gives me a higher FSB to play with, resulting bandwidth is much closer to the magic 10,000 so maybe a 1200mhz kit is worth it after all :yepp:

The OCZ Plat LV 9600s are available for about Ģ60 though ;)
I didn't notice them before I ordered my 9200 Blades. Oh well, I wouldn't reach 1200 24/7 anyway with this mobo + a quad.. and the blade's look f-ing cool :p:
edit: wait, did I just completely blank out when I read your comment :o because now I see you wrote that in your post anyway haha :D
They are Ģ60 but they aren't available ;) I'm still tempted just to go for 4GB of 8500, it's so cheap in comparison...
Yeah, I snagged some 9600LV when they first came out, I'd have 4G more if coulda found em by now personally.
Would of have gotten 8Gb, but the Egg would only let you get 4Gb at a time, I really like this RAM.
Got it up to 1248 the other day messing around knocking the CPU back to 3.75 and was pretty stable, hard to push the FSB on this Q9650 too hard I guess on air :)
I just bought the 1150 blades, coming tomorrow morning all being well. I want to keep the 5:6 divider so I might shoot for 478 fsb which gives me 4.3GHz and ddr 1147 - will do an everest bandwidth test tomorrow when I get the stuff set up. :yepp:
I tried the 4:5 divider only once so far and I couldn't even get to desktop, but maybe it was the BIOS. Is 4:5 a strong divider on the P45? I thought 5:6 was optimal.
Can't seem to boot at PL7 with anything lol - still have a lot to learn! :yepp:
I tried PL8 forgetting my memory was 1:1 with the FSB, so that's why my PC froze... oops :D
yeah PL 9 and tweak from there...
My 9200 blades arrived early this morning. :cheer: First boot @ 1150MHz with 1.8v in BIOS (everest reads 1.79v)
http://i293.photobucket.com/albums/m...ddr1150PL8.png
Second boot @ 1200MHz with 1.9v
http://i293.photobucket.com/albums/m...ddr1200PL8.png
Boot at PL10 both times, set PL8 in Windows. Not much difference between 1150 and 1200, certainly not worth roasting a nice pair of sticks over :D I'll be keeping them at 1.8v if at all possible.
Amazing memory. :up:
Hey dudes,
Sorry I'm being a bit lazy by not reading the entire thread :p: looking for some nice RAM to team with my E8600 and DFI X38 - aiming for 420MHz+ 1:1 CAS4.
Is this the kit to buy right now?
Cheers,
Su
I've settled on some numbers = 467x9 for 4200MHz, and memory is 4:5 at DDR 1171 with 1.84v. Will probably take that voltage down as I don't think it needs it.
I'd love to go for 4300MHz but I can't get the FSB stabe and the CPU is too hot, however at 4200mhz I get pretty much 10,000 mb/s on read, write and copy so I'm happy. :up:
LennyRhys - go for PL7!
I'll be trying some things out soon again I guess, had mine up to a pretty stable 4.15 the other day and kicked things around a bit, just have things really stable here atm and tired of testing for a bit :)
Have some new fans on the way to mess around with too I guess, gonna try to make this thing reasonably quite in the process and kick up the air at the same time.
The Arctic Cooler Accelero Xtreme's I highly recommend as an aside, put the 4870X2 version on my card a week ago, really works nicely. Takes a bit of work installing that guy heh. Cut temps in half and about 1/4 as loud on the GPU's.
:up:
Not trying to hijack this thread but I was curious about something and thought if anywhere someone here might know the answer. I have a Gigabyte ga-ma790x-ud4p mb and a few weeks back I tried the 1066mhz lv blades. For some unknown reason my MB wanted to overvolt these at auto setting to 2.05v. when I changed system voltages to manual it gave 2.05v also. If I adjusted voltage to +.1v I ended up with 1.95 volts (i known it should have been at 2.15). For some reason It sets the starting point .2v over what it should be and the + increments scale properly as if the starting point was 1.85v.
To my question, Will 1.95-2.05v burn out these sticks, they did not seem hot and I got very good results (1170mhz 5-5-5-15-23) on my rig. My mb/processor combo is finicky about what ram works in it and these work fine no errors in memtest or prime95 unless they are pushed alot higher than stock.
OCZ Blade LV 9200's 5-5-5-12 1175 1.8v @ PL7? :eek:
YES WE CAN! :up:
http://i246.photobucket.com/albums/g...L7yeswecan.jpg
Thats on a P35 though, I can run PL 7 on 3:4 but not 4:5 or 5:6.
http://i131.photobucket.com/albums/p...1/x3380pl7.jpg
So I got the PC9600's... But I am a bit dumbfounded by the speed at 333MHz (1:1) compared to the full 600MHz (5:9):
333MHz 5-5-5-18
http://i119.photobucket.com/albums/o...nch_oc/2-1.png
600MHz 5-5-5-18
http://i119.photobucket.com/albums/o...h_oc/1-1-1.png
By upping the frequencies to FSB 353 and RAM 617 (4:7) and increasing the VRAM to 1.85V (got a BSOD on 1.80) I did get an increase.
But the question remains: How can a 333MHz clock get such a high bandwidth?
http://i119.photobucket.com/albums/o...nch_oc/2-2.png
nForce chipset, that's why.
Normal rules don't apply to them...
Irony is, you will likely get best performance running them whatever the highest speed with tightest timings @ 1T, rather than highest speed like with Intel.
So something like DDR2-800 4-4-4 1T may very well be just as fast or faster.
Received my $51 shipped (now $47) Amazon OCZ Platinum DDR2 1066 Low Voltage set.
Not quite as stable as my Blade 9200's.
For 1.8v 1150's seems to be it for stress testing.
However, perfectly fine for my third rig.
Interestingly enough, black pcb's and Jedec 1110:
http://i246.photobucket.com/albums/g...at10661110.jpg
Got the 9200 Platinum low voltage kit (couldn't find blades in stock at the time) a few weeks ago. Could not post at the rated speed using a 5:6 divider so pretty much gave up on them. Put them back in to test again and with some help from a couple guys in XS was able to reach 1200mhz using the 4:5 divider. Working on 1236mhz now.
http://img525.imageshack.us/img525/9...imm1200mhz.jpg
Looks like after a few bsod's my date is not set correct but it was run today lol.
Hi there.
Postman brought me my blade 1200īs today in the morning.
SPD is only programmed till 400mhz, as my board doesnīt provides less voltage than 1.8V in the Bios and overvoltes to, Iīve 1.84 on the sticks according to everest.
http://www.overclockers.at/attachmen...hmentid=143548
Running Prime large at the moment as I havenīt tested higher fsbs than 420 b4.
If you want to stick to 10x420MHz for the CPU I would run the memory with 3:4 divider on 400MHz strap with CL5, that should be a bit faster than 420MHz CL4.
P35 can run a lower PL than P45 at the same FSB speed.
FSB speed has only been changed a bit, run a higher FSB and smaller divider, that will give you way more bandwidth. And as mentioned by -n7-, nVidia chipsets are different, the normal rules for Intel chipsets don't apply there.
Try at least 400MHz FSB with 2:3 divider, then run Everest bandwidth test and report back ( please include MemSet in your screenshot ) ! ;)
I can't run over 450MHz FSB. Weirdly I have a BIOS that has a 1.4V max on the VTT, and when I exceed even to 460Meggerhurts the system gets unstable.
Here's my satisfying run of DDR2-900 @ 4-4-3-12 1T :D
http://i119.photobucket.com/albums/o...ch_oc/th_8.png
Nearly 10k mhmm nice
Thatīs whatīs my rig is doing at the moment...
http://www.overclockers.at/attachmen...hmentid=143567
Edit: Bad Idea crashed after 20 minutes..
NVidia Chipsets have some mean strap changes where perfomance drops significantly at a certain FSB-speed. I know you want to reach a high CPU-clock, so these settings are optimal for you, but for highest Everest scores I still think you could find better settings.
Try 395MHz FSB 2:3 divider and run Everest and then 405MHz 2:3 divider.
I would like to know if 780i is still like 680i was.
My guess, tRD=6 at 450MHz FSB might be a bit tight...
Hi 18, nice to see you here :)
I have NO idea. I downloaded MemSet from three different sources, and this is still all I get:
http://i119.photobucket.com/albums/o...ysbuild/12.png
Where are all the other settings?!
Weird. I guess it's a mobo thing.
With my Abit Pro, I couldn't change anything with Memset.
680i does not have tRD/PLs, or to be more exact, you can't influence it manually, that's why I said it does have some mean strap changes. ;)
On 680i memory bandwidth is very dependend on CPU clock, not really much on FSB once you passed a certain speed because of the aforementioned strap changes. It shines on read and latency, but write and copy scores will always be lower than on Intel chipsets.
Which other settings?
That's all you will get from it, be happy that you have tRC, that's a timing I miss on my Intel chipset, because it will help you generate more bandwidth. The problem is that you can't force a certain strap.
I will PM you some important threads and more info tomorrow, I'm too tired now and it doesn't belong here anyway... Okay? :)
It's not a Motherboard problem, you are all not familiar with nVidia chipsets, they are totally different from what we are used to on Intel chipsets. ;)
So if I really want to get the most out of my memory, what must I change? I am not familiar with any of the lower values...
EDIT: LOL wow I didn't know you're from germany too! :D
He might be asking that because I was asking him about it for my board.
I want to totally get some of this ram, but I'm not sure if will really help me that much. I've never seen this PL stuff. I was about to power down and go look for the PL and see what I was set at til I read the guy above not finding it.. I have the 750i FTW, and I used to have G-skill 1000 Mhz that COULD NOT even do that, but the Current Corsair Dominator 2x2GB 8500's run fine on 1066 and CL5. but I've not really tried for much higher, I think I'll give it a try now.
I've never messed with the strap as much as all you guys are saying here. I've done it, but changing the strap on a Nvidia board is completely different than on the EP45's. I had the pleasure of messing with the EP45 and some regular 1066 Mhz Blades and I got a Q6600 to 3.4 Ghz and the blades to 1120 within minutes stable as can be, I've not messed with it since. It's in the other room right now..
I'm wanting to get some Blade 9200's but I'm not sure how my 750i will take all this jazzz. so I don't know. Maybe I'll do what I saw another guy do and go for a decent speed and a tight timing. some 4-4-4-12 1.. but IDK.
edit* ya I'll go mess with my ram right now. as I've not really done to much with them cuz I'm at a nice stable spot right now running 4.0 Ghz with 444FSB with a 5:6 strap for 533 Mhz CL5
When I had my 680i board + cellshock D9GKX I was getting better memory bandwidth than some guys with DDR3 - high FSB and 1:1 divider rocks on these chipsets.
I had my shocks synced with the fsb at 475mhz: 950mhz 4-3-3-10, read was over 12,000mb/s, write was 10,200, and copy trailing at 8,000.
I really want to make 10,000 in all three columns but I have to push my blades to >1200mhz for that to happen and they need 1.9v, and seeing that EVP is only 1.85v... :(
Here's 10k across the board, but 1205 mhz :eek:
http://i293.photobucket.com/albums/m...kbandwidth.png
Hey guys, it's my second day with my OCZ Platinum LV PC2-9200's...
I had to lower all my boards drive strengths to minimum to get these stable. :lol:
I don't have to much money and parents don't understand why I bench or like computers so much so:
I've got Everest Numbers but no screenshot: (Ran tests separately)
Memory Read: 10468 MB/s
Memory Write: 9485 MB/s
Memory Copy: 11125 MB/s
Memory Latency: 38.3 ns
Specs in sig, I'm currently doing 1100 5-5-5-12 2T tRC 17 @ 1.81v
System will not post @ 1100 5-5-5-10 2T tRC 15 @ 1.83v... Somehow completely stable at the above though.
Of the numbers or the timings? Again, I'm using the trial version and had to run them separately but I can give 4 little cut's from screenies if you want me to.
Anyway, I'm not lying...
http://img505.imageshack.us/img505/235/everestd.jpg
That's crazy memory bandwidth from an older cpu/mobo. :yepp:
Thx LennyRhys...
I'm thinking about taking the CPU multi down to 9x and clocking the hell out of the FSB for a bit, see how far I can take the ram...I'm not close to it's limit, but I'm at my CPU's limit. 3350 is only good for 1M Pi runs but 3300 passes OCCT Small/Medium/Large for 2 hours each.
1:1 is best if your mobo can get the FSB high enough.
I've broke 10k read and 11k write and copy with ram at 1080 1:1. 24/7 stable I might add.
This is just cheap $35 micro center special stuff though
http://img268.imageshack.us/img268/7066/10gbz.jpg
Well, it has it's advantages and weaknesses. Most of these 590 SLI boards won't even get past 1000. (Of course, without Xtreme tweaking.) When I popped these in for the first time I could not even boot into Windows 7 64-bit @ 6-6-6-18 1040 Mhz 1.85v.
Gotta love the latency though...nearly half of intel platforms and just the same or more bandwidth at 2T.
OCZ2P1150LV4GK arrived!
w00!
It's been far too long since n7 last had new RAM to play with. :D
New babies!
http://ense7en.com/pics/OCZ2P1150LV4GK/packaged.JPG
Lined up with my Mushkin.
http://ense7en.com/pics/OCZ2P1150LV4...0by%20side.JPG
I'm too scared to ruin the fun by putting in all 8 GB at once, so i'm playing with kit #1 for now.
Subtimings aren't tweaked, so if i was worried about numbers, i could get Everest a bit higher. Not the concern for now though.
DDR2-1200 5-5-5-15 1.8v (tRD 8) good for 5 passes of LinX.
http://ense7en.com/pics/OCZ2P1150LV4...5%20passes.JPG
Ooh...same kits I just started playing with. :) Of course I've got 1125 MB/s copy 10868 MB/s read and I'm only @ 1100 5-5-5-12 1.81v :D
To me, it's the bandwidth that counts...too bad, my CPU and motherboard are limiting. I also prefer these heatspreaders over the blade ones. I like shiny. :lol:
Try PL7 and PL6 when you get the chance......I'm pretty sure this RAM can do a lot more than 1200 and was only stable at my motherboard's lowest drive strength settings.
Your tRC is too tight in my opinion. Do you have a possibility to change tRFC?
If not try a higher tRC ~30, as by JEDEC spec tRFC >= 2 * tRC.
These kits need high tRFC to reach high clockspeeds.
So you finally got some too.... :D
Looking forward to more results!
High mhz/lower fsb is much better than 1:1 on P45 - here's 4:5 at 525 FSB vs your 1:1 at 540 fsb :yepp:Quote:

Best I got out of my Blades was nealry 9.6k rad, 9.4k write and 9.6k copy with 450 fsb and 600 ram. Sadly thatīs with PL6 which is non by far stable.
Nope, you can't change tRFC on AMD. And I gain a good 150 MB/s going from 26 tRC (Auto and maximum) to 17. It's a good trick if the ram runs stable. My main issue with clocking was the drive strength. They were set on auto, And going down it was like: 1.50x 1.50x 1.50x 1.50x 1.0x 1.0x
Now they are all 1.0x so I had to lower 4 of them about 50% to get them to run correctly. :shrug:
My board is generally known to overvolt on vDIMM by about 0.08v.
So 1.8v is likely around 1.88v.
Below is pretty much the highest i could get with the first 2x2 GB.
I imagine i could get higher with more vDIMM, but i'm not going over 1.8v for these.
DDR2-1230 5-5-5-18 loose subtimings (not stable)
http://ense7en.com/pics/OCZ2P1150LV4...er%20tRD-8.JPG
I actually had better luck on the 266 strap (2:3) than on 333 (5:8), which was weird. On 5:8, i couldn't even get into the OS @ DDR2-1230 5-5-5.
I tried 6-6-6 as well, but it did not get me anywhere.
Couldn't even boot into the OS w/o missing files or BSODs @ DDR2-1250.
So no scaling with CAS 6 at all :(
Really too bad...
DDR2-1215 5-5-5 i could still get thru 5 passes of LinX, but that was about it.
http://ense7en.com/pics/OCZ2P1150LV4...5%20passes.JPG
Here's as good as it's going to get for me in Everest:
http://ense7en.com/pics/OCZ2P1150LV4...ap%20tRD-8.JPG
I've now put the second kit in for 8 GB.
Headache has begun with 8 GB, as usual.
With 8 GB, just in Memtest86+ alone, DDR2-1160 or higher is not stable :(
So as i'm not willing to go over 1.8v for now, my dreams of DDR2-1200 8 GB are pretty crushed.
Trying to get things stable with 8 GB @ 4:5 at this point.
9x456 1.24375v (4104 MHz) LLC enabled
4:5 266 strap (DDR2-1140 5-5-5-18-60) Clock Twister @ Lighter tRD @ 8
HCI 4x1400 MB 300% stable & LinX max RAM 25 passes stable.
Course, after these two, i got a BSOD just while surfing the web...really hoping that was because i just need more NB voltage or vcore (LLC bumps vcore up quite a bit under load, so it's actually a lot lower idle).
http://ense7en.com/pics/OCZ2P1150LV4...0%20300%25.JPG
That's because 6-6-6 is evil :devil:Quote:

Very tempting.
tRC was good to generate bandwidth on 680i too where you didn't have tRFC either, but can you get a higher overclock at a higher tRC?
I had big problems on 5:8 divider too, very weird. I couldn't boot at anything over DDR2-1160, though almost DDR2-1200 was stable in Windows when I setFSB'd to that speed.
I might get a kit of these when I'm done testing my aXeRAM. I want a 4GB kit that can do 1200+MHz.
All last night i was fighting, trying to get 8 GB higher.
In Memtest86+ test 5 quick checks, i was able to get past DDR2-1140, but the problem is Memtest86+ getting errors doesn't mean things are actually stable when it comes to 8 GB.
4 GB is seriously such a piece of cake for overclocking LOL.
8 GB...such a different annoying world, at least if you are really testing for stability.
So yeah, in Memtest86+, i had DDR2-1173 5-6-5-18-70 get thru a few test 5 runs.
DDR2-1187 5-6-5-18-70 1.82v also.
But it wasn't stable in the OS, & having to use 400 strap (3:4) puts out worse Everest numbers than 266 strap (4:5), so running say 9x450 DDR2-1200 is hardly any faster than 9x456 DDR2-1140, not to mention i cannot get as high with CPU using 3:4 either.
9x450 3:4 (DDR2-1200) - this i cannot do with 8 GB, but it shows the numbers.
http://ense7en.com/pics/OCZ2P1150LV4...5%20passes.JPG
And here's what i'm currently running
9x456 4:5 (DDR2-1140)
http://ense7en.com/pics/OCZ2P1150LV4...%20everest.JPG
Faster CPU speed more than makes up for a tiny loss in Everest numbers.
And it's doable stably.
http://ense7en.com/pics/OCZ2P1150LV4...0%20160%25.JPG
So in short, n7 is settling with 4:5 operation, which means DDR2-1112 to 1140 range depending on whether i sit on 4 or 4.1 GHz.
Anything over 1200mhz seems to be very hard with this set. Using 4:5 divider pl8 on the UD3P board.
http://img189.imageshack.us/img189/2594/pc9200.png
n7: Nice vcore BTW for 4.1ghz. :up:
Me too, at least more.
Egg and their silly you can only buy freaking 4G at a time stuff :)
So what is the most important score on the everest test, the copy?
I don't have the blades (I'm getting them soon) but for now, I have some decent scores on my stuff at stock 1066 Mhz, so I was wondering what I need to change. In everest I got
Read: 10940 Write: 9424 and Copy: 8069.. everyone else in this thread have closer numbers. like all in the mid or high 9's. why is my read so much better than copy, how can I even that out. I'm running 1066 Mhz 5-5-5-15
I just tried to run memset 4.0 and I got some error about that I must use Normal Size 96ppp in this software, please go to office>properties> change to normal or some junk. whats that about. lol
well I was able to get over 11K on read, and 9600 on write, and just under 9k on copy with a few timings changes.
Same here, but it's enough for 600FSB :p:
http://i210.photobucket.com/albums/b...baraba/600.jpg
Newegg shows 9600 Blades deactivated????http://www.newegg.com/Product/Produc...82E16820227455
weird, yesterday they showed an ETA 7/31
Now they are not listed at all. I think my next set if I stay with this platform a while longer will be the GSkill 1200's. Seem to be very good ram. I HATE to pay 139 for ddr2 ram but have never heard a bad thing about them from anyone that uses them. I need to be able to use the 240b 5:6 divider to run 500fsb~1200mhz. I can only use the 250A 4:5 divider or 1:1 with this set of OCZ platinums, at 500fsb 250A it puts my ram at 1250mhz and windows laughs at me on boot.
I just ordered some PC-9200 Blades for Ģ57... man you guys get stuff so damn cheap, it's unfair :p:
Has anyone played with the 9200 blades? I may be stuck with getting a set of them but I'm not interested if they cant do 1230MHz or so :p:
-n7- got the Plats. http://www.xtremesystems.org/forums/...&postcount=459
Hmm.. thats pretty crappy given the extremely marginal price difference between the 9200 and 9600 kits. Looks like I'm back to waiting for somewhere, anywhere to get the 9600 kits back in. I looked at about 20 e-tailers now, all out of stock.
For $44, those 1066 Plats are very tempting.....http://www.amazon.com/OCZ-PC2-8500-P...f=pd_rhf_p_t_1
My 1150 Platinum kit does not post past 1160. :(
On the bright side, it does not change when I add voltage so I guess it's not the ram.
I have a bad feeling about this. Probably the 9600 is history...
Only available provider:
http://www.amazon.com/dp/B002ASHVXE/...0&linkCode=asn
"Usually ships within 1 to 3 months" :lol:
http://www.amazon.com/dp/B002ASFRK8/...0&linkCode=asn
I'm guessing they hit a bump in the binning process. I don't think it will be history (yet) but there may be about 3-4 more weeks before we see them again.
Well, I assume that if you push 1.85v-1.9v into the 9200's they should top out around DDR2-1250... that's just my guess. I can't test because my motherboard is a pita.
BeepBeep2: I was hoping so also but at just over 1200mhz it becomes unstable even at 1.92v. I was able to get 1200mhz stable but with 480fsb 4:5 divider on 1.84v but after that voltage doesn't seem to help. I doubt it is this motherboard but I could be wrong..
at the price the gskills are now its sensless to but any lv kit
i paid 300$ for my skills
and i gotta say they were the best ddr2 ever made absolute best
1260mhz for 24/7 was a peice of cake even 1300 was good for 24/7 n they never even got warm
was a pleasure to play with them gskills while i had em
It would be nice if I had a good mobo/CPU to actually push these sticks with...
I've got the same results 1.78-1.85v so I'm 110% sure it's my CPU's IMC.
I also tried 5-5-4-10, well...it posts, and boots. So I tried 5-4-4-10. BEEEEEEEEEEEEEEEEP BEEEEEEEEEEEEEEEEP....I reset the CMOS for about the 5th time the day. I just BSOD'ed in GIMP with 8 7MP images open @ 5-5-5-10 1100 Mhz.
Tried posting 2900 Mhz/DDR2-1160 earlier and it hangs on POST. (Passes, reads mem clock speed then won't detect HDD's etc and becomes unresponsive) Does the same from 1.78v to 1.85v.
I'm just out of money, and bought an OEM copy of Vista so I can't use a second mobo/CPU. So sad.
