Ratio 1:1 important?

[erdinger]

Hello I've overclocked my cpu a few weeks ago and now I'm asking myself if my ram is running to slow.

Mainboard:asus p5b (no deluxe just p5b)

Core: Intel C2d E6300 @ 2.33 ghz (fsb increased to 330 from 266) STOCK COOLER

Ram: Kingston value ram 2x2gb kit cl5 ddr2-800

now the problem is that I've downclocked the ram to get a 1:1 ratio with the fsb.
(ram actually running as ddr2-666)

I'm asking my self if i got better performance, when increasing to ddr2-800 (-- and would core temps increase?)

This questions might sound silly, but I really don't know how important the 1:1 ratio is and what the new ratio would be.

Another question. If I increase to ddr2-800 in the Bios could it be that it automatically overclocks my Cpu to match so?

Since I'm using the stock cooler this would most propably burn my cpu.

Thank you for your answers
your Erdinger.

I've found out that with fsb 333 and ddr2-830 the ratio would be 4:5.
would that be better then my actual settings?
can ddr2-800ram do 830 without problems?

Thanks again

If you don't increase the fsb or vcore than temperatures shouldn't change.

1:1 fsb/ram ratio is great when not seriously under clocking your ram.

At a predefined frequency, a 1:1 ratio will always be faster than when running your ram through a divider. However, by drastically under clocking the ram, you lose the benefit of running no divider due to significantly less bandwidth.

In your case I would run the ram at- or close to rated speed, mainly because of the relatively low fsb your running.

 

[sportsfanboy]

You can always overclock it slightly like you want and run some tests.

Run prime95 in blend for a few hours and you'll have an idea if it's stable at that speed. Make sure you check "round off checking" in the advanced tab, or errors if any, will not manifest themselves.

 

[erdinger]

Thanks I'm trying that out now

Was playing for an hour or so and everything was working great. after I reckognized that prime was running while I was playing....

However my temperatures got pretty high, core0,1 46 and cpu 52 (speed fan)

strange that the cpu gets much hotter than the cores isn't it?

Can some else give me his oppinion?

4:5 333fsb ddr2-833 or 1:1 333fsb ddrs-667 whats better?
I remember that I've red somewhere that 1:1 makes less heat because of higher efficiency isn't that true?

 

[m_silkstone]

Heat and dividers have nothing to do with each other.
I would go with 833 - But you can test them both. get everest and do a memory benchmark to see which is faster.
Core temp of 46C at load is excellent - nothing to worry about at all.

 

[erdinger]

I don't worry about core tems but about cpu temp reaching 53... it's winter and cold in my room in summer it could get weigh hotter... than the cpu would reach more than 60* an BURN. right?

 

[zenmaster]

1:1 is good but not imperative.

Often you can Drop your CPU multiplier which lets you raise your FSB and run your RAM at a native 1:1.

So if you don't want to run your CPU faster than say 3.0ghz for a given reason but that leaves your RAM slow at 1:1, simply drop the multipler and increase the FSB.

A faster FSB will speed up performance even if the CPU does not go faster.
(Not a massive gain, but a gain nonetheless.)

 

[grieve]

I would run the ram @ 667 --> 1:1 and tighten the timings

 

[erdinger]

omfg speed fan says (idle) core0+1: 36* and cpu:90 what the hell....

I'm shutting down althoug I think that proves that the number is wrong.

 

[m_silkstone]

60@load isn't anything to worry about. when it get's into the 70's then you'll be getting errors and blue screens

Erdinger, speed fan reads sensor data from a number of places. Core 0,1 should be the only ones to concern you. Even though it says CPU, I don't think it is really meaning your CPU (it would probably have melted by now LOL)

from the SpeedFan page
There are several ways to label available readings (temperatures, voltages, fan speeds). The first source should be the BIOS. Enter BIOS at boot, write down labels and readings and compare them to those reported by SpeedFan. You can use manufacturer's custom hardware monitors to match readings too. SpeedFan strictly adheres to available datasheets for each sensor chip. Please remember that hardware monitors chips have some pins (small connectors) that should be connected to some additional hardware (temperature probes, thermistors or thermocouples) in order to be able to read temperatures. Only a few hardware monitor chips do label their connectors with "CPU", "System" and the like. Most of them use labels like "Temp1", "Local" or "Remote". Hardware manufacturers connect available pins to different temperature sensors basically according to the physical placement of components on the motherboard. This means that the same chip, an ITE IT8712F, for example, might be connected to a sensor diode measuring CPU temperature on Temp2 and, on a different hardware, it might be connected on Temp1. If you have a "Local" sensor and a "Remote" labeled one, this usually means that "Local" is the temperature of the monitor chip itself and "Remote" is the temperature read from a "remote" probe. When you have properly identified which temperature sensor is which, try to lower the speed of each fan and look at reported speed and temperatures. This way you can match PWM controls (speeds) with fans. Please, note that if you do not allow SpeedFan to change any fan speed and set all the speeds too low, then SpeedFan won't be able to avoid overheating.

try using realtemp or coretemp

K thanks I'll ignore the other numbers from now on... had a little shock but I also knew that 90C just can't be.

I've tested the system with everest ram and cpu benchmarks and the results looked either the same oder better for ddr-830 so I'm staying with ddr2-883.

Another question, how much would a good aftermarket cooler cost that could cool my E6300 really good?
As I heard it could get up to 3.2 ghz and even further, that sounds great but I don't really want to invest somethin.

 

[eclipseaudio4]

one thing you can do to increase the stock coolers ability is to polish it. Another is to cut a hole in the side of your case and add a tube so that it sucks in air from outside the case. This will dramatically reduce all of the tems in your case, I just did so and went from 40 idle 55 load to 30 idle and 47 load.
And my MB and GPU dropped 2 degrees as well. and all from one little hole.

 

[erdinger]

My Case already has a "whole" and a tube for the cpu cooler...
still if I overclock it to 2.6ghz it reaches 52C pretty fast

I agree with running ddr667 @ tighter timings and 1:1 ratio. You'll see higher theoretical bandwidth numbers in tests like Everest and Sandra if you clock your RAM to 833, but on my system I get higher fps and generally snappier performance from ddr667 @ tight timings. Of course ideally you would run a 1600mhz fsb with your RAM running full speed and still at a 1:1 ratio. In my case this puts my cpu @ 3.2Ghz which increases my temps too much in my small media center case. With your cpu that would put you @ 2.8Ghz. That is very doable in a full size case with an aftermarket cooler. Arctic Cooling Freezer Pro 7 is like $25 on Newegg and would do the trick.

 

[erdinger]

Arctic Cooling Freezer Pro 7 is exactly the cpu cooler I was thinking of.
I increased the fsb to 350 so that the ram runs at ddr2-700, the performance is good and I'll leave the timings on auto because last time I messed with them my pc had problems booting and I had to reinstall windows (after 2 years of active use without any problems) which was pain in the ass.

Thank you for your help but I think the question is answered and the topic can be closed

 

[kyeana]

the arctic freezer 7 pro isn't that great of a heatsink, nothing compared to some of the other coolers out there (like a direct heat pipe one). For the best performance heatsink i would recommend a xigmatek s1283 (assuming your mobo/case can fit it).

If you want a list of good heatsinks and their results go to www.frostytech.com and look at the top 5 heatsinks sections

Edit: spelling

 

[erdinger]

Am I think you wanted to say Xigmatek s1283 right?

 

[kg4icg]

here is a little example of me running 1:1

and yes I have speedstep on

lol yep Thanks for fixing that

Ive been reading alot in the forums here and all the people have really high voltages. I overclocked my E6300 to 2.45 ghz (from fsb 266 to 350) the sistem runs stable and the VOLTAGE IS AT THE SMALLEST VALUE POSSIBLE with my motherboard. Temps reach 48C under load. Cpu-z says 1.84V, why do all the other people have to increase the voltage when increasing the fsb and I can even decrease it? (I also have all energy saving options on)
