got 3200+ venice to 2.7 but would like to take it higher

[fluxquantum]

hello everyone,

i got my venice to 2.7. the specs on my system are in my sig. what will i have to do to get it to 2.8? i kept the ram timings at 2-2-2-5 (default voltage) and increased the cpu voltage to 1.525. ran prime95 all night with no errors.

10 x 270 = 2700 MHz is what i am currently using. i did 10 x 280 but the system just reboots and doesn't get into windows. i am not sure what to tweak in order to take it higher. any suggestions would be appreciated 🙂

 

[theMan]

what divider are you using, is your ram speed at 270? if so, thats really sweet. anyway, you should set your vcore to 1.55, and set the memory divider low. then, see if you can do 2.8. once you prime 2.8, you can raise your memory divider and see how high it goes. i recommend using gogar's a64 oc calc: http://math.gogar.com/athlon64.cgi?showtable=1&htt=200

 

[dainthomas]

Also make sure your HT multi is set to 3.

Nice OC, but I don't know if I'd go much higher on the voltage for just another 100mhz.

 

[theMan]

nah, 1.55v is perfectly fine, and the cpu will last untill it is completely obselete.

 

[fluxquantum]

LOL, i'm posting at work but i was eager to see what others recommended and couldn't until i got home🙂 thanks for your reply. yes, my ram is running at 270. i probably need to adjust my memory divider. this is the part that confuses me. my bios says the memory is at 266 MHz. i can change this correct? what about the 1T/2T deal? that part confuses me too.

 

[theMan]

ok, its best to use cpu-z to see what its running at. you probably want to set it to the 166 (ddr333) divider. make sure you arent ever using 2t timing. NEVER. then, see if you can get even above 2.8.

thanks. i appreciate the tips. i will post back later with some more results as soon as i get home. 🙂

It probably means that you are running the 266 divider, which means that ram should now be at approaching DDR400 speeds (180mhz, DDR 360 effective, if I can do my math right), which is completely fine and I wouldn't push that much harder (like switching to a higher divider). You are doing really awesome, you can see how my venice has faired in my sig. Don't be afraid to push the voltage, but at the same time be careful and don't expect too much more. You have an awesome CPU/Setup the way it is right now 🙂

you are probably right. i should just be happy with a fine overclock and not be so greedy😛 thanks everyone for giving me some knowledge on overclocking. this is my very first amd system and i am very pleased so far.

Guys, I will actually be doing something very similar to what flux did. I plan on buying the 3200+ venice and overclocking it to about 2700mhz. I have a few questions though:

1. The RAM I will buy must run at 270MHZ from what i understand to keep it 1:1. So does this mean it will have to be DDR 540?

2. I plan on getting 1 gig now and another gig later, will this decrease performance (because all 4 slots will be taken up)?

3. What kind of RAM would allow me to do what i want to do.

I will have the NF4 Lanparty SLI motherboard

Thank you for you help

hi entropy,

i am not very up to date on the DFI motherboards but i know they seem to be the preferred overclockers' motherboard although i have had good luck with my asus mobo. i believe having 4 memory sticks vs. 2 does hinder overclocking ability. here is the memory that i bought.

OCZ

Thanks for your answer flux,

So this RAM would go to 270mhz without a problem and still keep decent timings?

Also would this be better for me than getting 2X1GB of some other type of RAM (obviously slower) and why?

Thanks a lot

i have had good luck with my OCZ ram with 270 mhz at timings of 2-2-2-5 with no voltage increase. of course i only have 2 x 512 MB sticks. according to many on here, if you want to go with 2 GB of memory, you should get 2 x 1GB sticks so performance is not hindered. i don't know the exact reason so maybe someone can explain. the only reason i didn't go with 2 GB is because of my budget. eventually i would like to get 2 GB, but i would definitely get 2 x 1GB sticks instead of 4 x 512 MB sticks.

here's a good thread to help you out. others out there know a lot more than me. i'm still learning as you are 🙂

See my only problem is would that 2GB of value RAM even go to 270mhz? Because there are no high performance 2X1GB modules

that's a good question. i'm not sure if any 1 GB modules will do that speed. although someone from that thread pointed out an interesting fact.

Your options are

1) Get another 2x512MB and run 4x512MB. Running four sticks is said to reduce stability, but this is mostly an issue with crappy motherboards and overclocked systems. Your memory is only as stable as the weakest chip and the board's ability to make them get along, so this is a real issue to people pushing their memory speed/timings. Running four sticks also forces your system into 2T command rate, and although there's a nice thread proving saying it's not that big a deal, it's something to avoid if you can.

2) Get a single 1GB stick, and then you'd be running three sticks of mixed memory. Does that even work in dual channel on an A64 like it does on the NF2 chipsets? Even if it does work, it's not better than the first choice, so you'd be better off saving some money and staying with 2x512MB (since it's cheaper than 1x1GB)

3) Sell your 2x512MB and get 2x1GB. This is the best choice if it's not too much of a hassle.

If you're not overclocking or anything, though, and you have two empty slots, there's really nothing wrong with just getting another $80 2x512 kit. It's $20 less than a 1GB stick, and you're not going to notice the difference. I'm using a 1GB stick so I can upgrade to two 1GB sticks later, but that's really just because I'm a big geek and worry about a lot of stupid little details that don't make much difference (just like 90% of the people on here which is why most people will tell you to ditch your old memory). In reality it's no big deal.

Going back the 2.8 issue..

I'm able to hit 2.8 with my 3000+ Venice after upgrading from a Gigabyte K8NS to the MSI K8N Neo4-F, but only at 1.6volts, so I'm a little unwary at running at that voltage long term..

My maxes are:

9x312 = 2808mhz with the 140 mem divider (RAM = 216mhz 2.5-3-3-8@1T) 1.6v
9x306 = 2754mhz with the 150 mem divider (RAM = 230mhz 2.5-3-3-8@1T) 1.55v

I think I'm going to opt for the latter setup, as the +50mhz CPU and -15mhz RAM is pretty much a wash in any real world scenario, and isn't worth running at extra volts/temps. Avoid the 133 mem divider at all costs, never go lower than 140.

In regards to your RAM question, last I heard 1GB chips were more difficult to OC than 512 modules. I imagine at the end of the day, it's also a wash between using 1GB modules and 4x512 in terms of which one is a more hassle-free OC setup (that is unless 1GB modules have dramatically changed in the past month). When I put my system together a month ago, no one was recommending 2GB except for Photoshop, then BF2 comes out and wham! everyone suddenly jumped on the 2GB bandwagon.. 😕 :|

 

[Shimmishim]

it's not required to run 1:1

if i were you and you REALLY wanted 2 x 1 gig modules, just run them with a divider...

according to zebo's sticky, a divider doesn't hinder performance very much in real life applications...

also... the newer LBBLE 052X don't seem to be clocking as well as the 0512/5/7 chips... but there are some that have been hitting 2.7....

2.7 is very optimistic... don't be discouraged if you can't get that... it's all luck sometimes in terms of the chip you get...

 

[blckgrffn]

He already got it, if you didn't read the OP 😉

 

[furballi]

DDR500 or faster may give you 270MHz RAM speed.

 

[fluxquantum]

well, it looks like my limit is 2.7 GHz, which is fine. my memory is probably limiting me but i'm still happy. it's a decent overclock and i can't complain. i took it to 2.8 with various settings and it was still a no go. i couldn't even do 275 x 10. so is a 266 divider okay? also i had to take my HTT to 3x, which is 810. This is not hindering performance, correct? thanks for all your help guys. 🙂

 

[furballi]

You should be able to run the memory at DDR333 (5:6 memory divider) with a 270MHz FSB. This would translate to a RAM speed of 225MHz. My Corsair Value Select can hit 229MHz RAM speed at 2.5-3-3-8-1T and 2.7VDC DIMM.

3x will be fine, although my AX8 board will also run at 4x with a FSB of 275MHz (1100MHz).

 

[AkumaX]

266mhz fsb = 133 = 3:2 cpu/ram ratio = 2 x 270 = 540/3 = 180mhz fsb = DDR 360 @ 2-2-2-5? or are you really running it at DDR540??

 

[Mattd46612]

Might be able to bump the HT to 4...

it's a pretty nice overclock in any event

thanks for the reply. i bumped it up to 4x and even 5x and it runs stable as a rock. i did some more prime95 overnight and it's solid.
