[New] Vostro V13

Well I've found out some interesting things about my V13.

The SU7300 CPU 1.3Ghz, actually runs at 1.6Ghz unless you apply a CPU intensive task. It does this by increasing the multiplier from 6.5 x 200, to 8 x 200fsb. I assume however that this will be just one core.

I ran Primetime on it, and it then went to 1.3ghz. Which will be both cores. Max temperature I got after 10 minutes was 54 degress C.

I also found out that the modified SetFsb that was discussed earlier does not have any effect on my 64 bit Windows 7 V13.

The hard drive does seem to constantly spin with a noise that you can hear too.

 

To those that are talking about the fan noise and or wanting to open it up to replace the thermal compound I think you need to pay a little closer attention...

Do this:

In a quiet room power down the laptop so its completely off.

Now, put your ear next to the front of the system and push the power button.

You will hear the fan kick on on the LEFT side of the system for a brief moment and then go silent. The constant fan-like noise you hear from then on is the HARD DRIVE.

 

1, That's only a misjudgment by CPU-Z.
Because SU7300 supports SLFM (Super Low Frequency Mode), in idle situation, CPU's frequency drops from 6.5x200 to 8x100, for energy-saving. CPU-Z can correctly recognize multiplier as 8, but still thinks fsb runs as 200. So that's the problem. This bug has not been fixed yet.

2, That modified version of fsb runs well on win 7 32 bit.

3, Mine comes with a 5400rpm hard disk, relatively quiet. Just replaced it with a ocz agility 60GB. Even in a dead silence room, you wouldn't be able to notice that my laptop is running like crazy, if I didn't inform you beforehand...

 

Not exactly, if you quickly shake a pencil holding it on one side in front of the screen you may notice it's discrete positions (normally you'll see a uniform trail). This shows that backlit is flickering. This isn't always noticeable but this leads to more tiredness when working with the screen. This is why I asked someone to try either to look at the screen through the phone or to try shaking a pencil in front of the screen as I described. Some screens will flicker, some will not. So I'm interested how V13 screen will behave.

 

Now I've fitted a SSD I've noticed some cpu whine at idle. As RMclock does not support the chipset, is there any other way to disable going into c4 sleep?

 

Hey thanks for that information.

So do you know if its possible to stop it from dropping, and instead just stay at 1.3ghz?

 

Silenced the problem by enabling bluetooth then disabling the power management for the module.

 

To get it to run under x64 you will have to put windows 7 in test mode so unsigned drivers can be used. The sys file can then be patched and the overclock will then work. Then use any of the many programs that can remove the test mode watermark.

 

Hi

I have no idea mate how to do what you suggested. Not even sure what it means to patch the sys file either. It would be great if it's possible to post some instructions?

Does putting it into test mode affect the general use of Win 7 64bit ?

 

Here is a link to a program i've used on x64 since the beta first came out.

You first enable test mode, reboot then patch SysInfoX64.sys using the same program again. Reboot then run OC_RTM875T_250.exe. The bus speed should now be reported in cpu-z at 250.

Edit: CrystalCPUID has a signed copy of SysInfoX64.sys so test mode is not needed, just replace the file.
